(a+b)^3 + (b+c)^3 + (c+a)^3 -3(a+b)(b+c)(c+a) = (a+b+b+c+a+c)(a^2+b^2+2ab+b^2+c^2+2bc+c^2+a^2+2ac-(ab+ac+b^2+bc)-(ba+bc+ca+c^2)-(a^2+ac+ba+bc)) Now, after simplifying, (2a+2b+2c)(a^2+b^2+2ab+b^2+c^2+2bc+c^2+a^2+2ac-ab-ac-b^2-bc-ba-bc-ca-c^2-a^2-ac-ba-bc) Now, after CANCELLING the terms and simplifying, (2a+2b+2c)(a^2+b^2+c^2-ba-ca-bc) After further simplification, 2(a+b+c)+a(a-b) +b(b-a) + c(c-b) {FINAL ANSWER} PLEASE mark me as brainliest..

Answer»

Answer:

2(a+b+c) + a(a-b) + b(b-a) + c(c-b)

Step-by-step explanation:

In this question, we are gonna use the identity of a^3 + b^3 + c^3 - 3abc = (a + b + c)(a^2 + b^2 + c^2 - ab - bc - ca).

(a+b)^3 + (b+c)^3 + (c+a)^3 -3(a+b)(b+c)(c+a) = (a+b+b+c+a+c)(a^2+b^2+2ab+b^2+c^2+2bc+c^2+a^2+2ac-(ab+ac+b^2+bc)-(ba+bc+ca+c^2)-(a^2+ac+ba+bc))

Now, after simplifying,

(2a+2b+2c)(a^2+b^2+2ab+b^2+c^2+2bc+c^2+a^2+2ac-ab-ac-b^2-bc-ba-bc-ca-c^2-a^2-ac-ba-bc)

Now, after CANCELLING the terms and simplifying,

(2a+2b+2c)(a^2+b^2+c^2-ba-ca-bc)

After further simplification,

9.	11) similary A (B nc) = (A-B) u (A-C)
Answer» Answer: A - (B n C) = (A - B) U (A - C). <P> Step-by-step explanation: For any three sets A, B and C, we are given to PROVE the following : A - (B ∩ C) = (A - B) U (A - C). We know that any two sets P and Q are EQUAL if and only if both are subsets of each other, that is P ⊂ Q and Q ⊂ P. Let us consider that X ∈ A - (B ∩ C) ⇒x∈A, x ∉ (B ∩ C) ⇒x∈A, (x∉B or x∉C) ⇒(x∈A, x∉B) or (x∈A, x∉C) ⇒x∈(A-B) or x∈(A-C) ⇒x∈(A-B) ∪ (A-C) So, A - (B n C) ⊂ (A-B) U (A-C). Again, let x∈(A-B) ∪ (A-C) ⇒x∈(A-B) or x∈(A-C) ⇒(x∈A, x∉B) or (x∈A, x∉C) ⇒x∈A, (x∉B or x∉C) ⇒x∈A, x ∉ (B ∩ C) ⇒x ∈ A - (B ∩ C). So, A - (B ∩ C) ⊂ (A-B) ∪ (A-C). Therefore, we get A - (B n C) = (A - B) U (A - C). Hence proved.

11) similary A (B nc) = (A-B) u (A-C)

Answer»

Answer:

A - (B n C) = (A - B) U (A - C).

<P>

Step-by-step explanation:

For any three sets A, B and C, we are given to PROVE the following :

A - (B ∩ C) = (A - B) U (A - C).

We know that

any two sets P and Q are EQUAL if and only if both are subsets of each other, that is

P ⊂ Q and Q ⊂ P.

Let us consider that

X ∈ A - (B ∩ C)

⇒x∈A, x ∉ (B ∩ C)

⇒x∈A, (x∉B or x∉C)

⇒(x∈A, x∉B) or (x∈A, x∉C)

⇒x∈(A-B) or x∈(A-C)

⇒x∈(A-B) ∪ (A-C)

So, A - (B n C) ⊂ (A-B) U (A-C).

Again, let

x∈(A-B) ∪ (A-C)

⇒x∈(A-B) or x∈(A-C)

⇒(x∈A, x∉B) or (x∈A, x∉C)

⇒x∈A, (x∉B or x∉C)

⇒x∈A, x ∉ (B ∩ C)

⇒x ∈ A - (B ∩ C).

So, A - (B ∩ C) ⊂ (A-B) ∪ (A-C).

Therefore, we get

A - (B n C) = (A - B) U (A - C).

Hence proved.

12.	if f(x)=x^4-2x^3+3x^2-ax+b is divided by x-1 and x+1 the remainder are 5 and 19 respectively, then find the reminder when(x) is divided by(x-2)
Answer» Answer: a = 5 b = 8 Remainder = 10 Step-by-step explanation: There is theorem known as “Polynomial Remainder Theorem” or “ Bezout’s Theorem”. It is Stated as - A Polynomial f(x) if divided by a linear polynomial (x-a) LEAVES remainder which equals f(a). So , getting BACK to our question - f(x) = x^4 - 2x^3 + 3x^2 - ax + b So , when it is divided by (x - 1) it’ll leave a remainder = f(1) = 5 (Given). f(1) = 1^4 - 2×1^3 + 3×1^2 - a×1 + b = 5 => 1 - 2 + 3 - a + b = 5 => a - b = (-3) …. Eqn(1) Now , Similarly - f(-1) = (-1)^4 - 2×(-1)^3 + 3×(-1)^2 - a×(-1) + b = 19 => 1 + 2 + 3 + a + b = 19 => a + b = 13 …. Eqn(2) Now , adding equations (1) and (2) , We’ll get - (a+b) + (a-b) = (-3) + 13 => 2a = 10 => a = 5 So , (a +b) = 13 IMPLIES b = 8 Hence , Values of a and b are 5 and 8 respectively. Hence, our p(x) = x^4 - 2x^3 + 3x^2 - 5x + 8 Now, Dividend p(x) = x^4 - 2x^3 + 3x^2 - 5x + 8 Divisor G(x) = x - 2 By using remainder theorem, we get, x - 2 = 0 => x = 2 By APPLYING the values of x in p(x), we get, (2)^4 - 2×(2)^3 + 3×(2)^2 - (5×2) + 8 => 16 - 16 + 12 - 10 + 8 => 2 + 8 => 10 Hence, the remainder r(x), when x^4 - 2x^3 + 3x^2 - 5x + 8 is divided by (x-2) is 10

12.

if f(x)=x^4-2x^3+3x^2-ax+b is divided by x-1 and x+1 the remainder are 5 and 19 respectively, then find the reminder when(x) is divided by(x-2)

Answer»

Answer:

a = 5

b = 8

Remainder = 10

Step-by-step explanation:

There is theorem known as “Polynomial Remainder Theorem” or “ Bezout’s Theorem”. It is Stated as -

A Polynomial f(x) if divided by a linear polynomial (x-a) LEAVES remainder which equals f(a).

So , getting BACK to our question -

f(x) = x^4 - 2x^3 + 3x^2 - ax + b

So , when it is divided by (x - 1) it’ll leave a remainder = f(1) = 5 (Given).

f(1) = 1^4 - 2×1^3 + 3×1^2 - a×1 + b = 5

=> 1 - 2 + 3 - a + b = 5

=> a - b = (-3) …. Eqn(1)

Now , Similarly -

f(-1) = (-1)^4 - 2×(-1)^3 + 3×(-1)^2 - a×(-1) + b = 19

=> 1 + 2 + 3 + a + b = 19

=> a + b = 13 …. Eqn(2)

Now , adding equations (1) and (2) , We’ll get -

(a+b) + (a-b) = (-3) + 13

=> 2a = 10 => a = 5

So , (a +b) = 13 IMPLIES b = 8

Hence , Values of a and b are 5 and 8 respectively.

Hence, our

p(x) = x^4 - 2x^3 + 3x^2 - 5x + 8

Now,

Dividend p(x) = x^4 - 2x^3 + 3x^2 - 5x + 8

Divisor G(x) = x - 2

By using remainder theorem, we get,

x - 2 = 0

=> x = 2

By APPLYING the values of x in p(x), we get,

(2)^4 - 2×(2)^3 + 3×(2)^2 - (5×2) + 8

=> 16 - 16 + 12 - 10 + 8

=> 2 + 8

=> 10

Hence, the remainder r(x), when x^4 - 2x^3 + 3x^2 - 5x + 8 is divided by (x-2) is 10

33.	(1) Determine the two numbers nearest to 700000 which are exactly divisible by 3, 9, 8 and 7.
Answer» Answer: 700000.11 Step-by-step explanation: The LCM of the two numbers= 3987 = 1512 Therefore any MULTIPLE of 1512 will be divisible by the 2 numbers. Thus, to find the number closest to 700000, we have to find how many TIMES to multiply to 1512. Thus, to this, we have to multiply 1512= 700000/1512 = 462.963 many times Thus, the number divisible by all 4 numbers to get a number closest to 700000= 1512 462.963 = 700000.11 approx Hope it helps Please mark me as brainliest

(1) Determine the two numbers nearest to 700000 which are exactly divisible by 3, 9, 8 and 7.

Answer»

Answer:

700000.11

Step-by-step explanation:

The LCM of the two numbers= 3*9*8*7

= 1512

Therefore any MULTIPLE of 1512 will be divisible by the 2 numbers.

Thus, to find the number closest to 700000, we have to find how many TIMES to multiply to 1512.

Thus, to this, we have to multiply 1512= 700000/1512

= 462.963 many times

Thus, the number divisible by all 4 numbers to get a number closest to 700000= 1512* 462.963

= 700000.11 approx

(1) A rectangular courtyard with length 7 m 20 cm and breadth 3 m 60 cm is to be paved with square stones of the same size. Find the least number of such stones required.

Answer»

━━━━━━━━━━━━━━━━━━━━

$\huge{ \sf{ \underline{ \purple{Answer...}}}}$

♠️ GiveN:

Length of courtyard = 7 m 20 cm
Breadth of courtyard = 3 m 60 cm
This courtyard is to be paved with square stones

♠️To FinD:

Least number of square stones required...?

━━━━━━━━━━━━━━━━━━━━

$\huge{ \underline{ \rm{ \purple{Explanation...}}}}$

In the question, it is given that the tiles are squares, so the sides are equal. It means the sides of courtyard is divisible by the side of square stones. For the minimum no. of stones, the side of the square need to the highest common factor (HCF) of sides of courtyard.

﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏ ✍

So, we need to find the HCF of 7 m 20 cm and 3 m 60 cm, this will be the side of the square. Then, we will find the AREA of each square stone and DIVIDE it by the area of courtyard to find the no. of tiles.

♦️ In this way, we will solve this question

━━━━━━━━━━━━━━━━━━━━

$\huge{ \underline{ \sf{ \purple{ Solution...}}}}$

First of all, we need to convert the sides into cm, for easy calculation or to make it easier to find HCF,

We KNOW, 1 m = 100 cm

Length of the courtyard = 7 m 20 cm = 720 cm

Breadth of the courtyard= 3 m 60 cm = 360 cm

﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏ ✍

♠️ The edge must be the common factor of the sides of the courtyard i.e. Minimum no. of stones = HCF of 720 cm and 360 cm.

Finding HCF of 720 and 360, by prime factorization

$\large{ \sf{\rightarrow \: 720 = 2 \times \red{ \underline{2 \times 2 \times 2 \times 3 \times 3 \times 5}}}} \\ \\ \large{\sf{\rightarrow \: 360 = \red{ \underline{2 \times 2 \times 2 \times 3 \times 3 \times 5}}}} \\ \\ \large{\sf{ \therefore{hcf \: of \: 720 \: and \: 360 = 360}}}$

So, MAXIMUM side of square tile = 360 cm

﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏ ✍

For finding the no. of square tiles ,we need to divide the area of the courtyard by area of courtyard

Finding the no. of required tiles,

$\large{\sf{ \star{ \: required \: no. \: of \: tiles = \frac{area \: of \: courtyard}{area \: of \: square \: stones} }}} \\ \\ \large{\boxed{ \green{\sf{ \ast \: area \: of \: square = side \times side}}}} \\ \\ \large{\sf{ \rightarrow \: required \: no. \: of \: stones = \cancel{ \frac{720 \times 360}{360 \times 360}}}} \\ \\ \large{\sf{ \rightarrow \: required \: no. \: of \: stones= \boxed{ \red{2}}}}$

✍Thus, the least no. of square stones = 2

11) similary A (B nc) = (A-B) u (A-C) ​

Answer:

A - (B n C) = (A - B) U (A - C).

Step-by-step explanation:

For any three sets A, B and C, we are given to PROVE the following :

A - (B ∩ C) = (A - B) U (A - C).

We know that

any two sets P and Q are EQUAL if and only if both are subsets of each other, that is

P ⊂ Q and Q ⊂ P.

Let us consider that

X ∈ A - (B ∩ C)

⇒x∈A, x ∉ (B ∩ C)

⇒x∈A, (x∉B or x∉C)

⇒(x∈A, x∉B) or (x∈A, x∉C)

⇒x∈(A-B) or x∈(A-C)

⇒x∈(A-B) ∪ (A-C)

So, A - (B n C) ⊂ (A-B) U (A-C).

Again, let

x∈(A-B) ∪ (A-C)

⇒x∈(A-B) or x∈(A-C)

⇒(x∈A, x∉B) or (x∈A, x∉C)

⇒x∈A, (x∉B or x∉C)

⇒x∈A, x ∉ (B ∩ C)

⇒x ∈ A - (B ∩ C).

So, A - (B ∩ C) ⊂ (A-B) ∪ (A-C).

Therefore, we get

A - (B n C) = (A - B) U (A - C).

Hence proved.
