Identify a pattern in the given list of numbers. Then use this pattern to find the next number. (More than one pattern might exist, so it is possible that there is more than one correct answer.)64, -16, 4, -1

Answer»

Answer:

Next number is -256

Step-by-step explanation:

Each number is being multiplied by -4

-1 x -4 = 4

4 x -4 = -16

-16 x -4 = 64

therefore 64 x -4 = -256

Each number is ALSO being divided by -4

64 / -4 = -16

-16 / -4 = 4

4 / -4 = -1

So another number will be -1/-4 = 1/4

3. Simplify: (2+3√2)²

Answer»

$\underline{\bold{Answer:}}$

$22 + 12\sqrt2$

$\underline{\bold{Step-by-step-explaination:}}$

$\text{The given number is }(2+3\sqrt2)^{2}$

$\text{We know that }(a+b)^{2} = (a^{2} + b^{2} + 2ab)$

$\text{Here }a = 2\text{ and }b = 3\sqrt2$

$\implies \boxed{(2+3\sqrt2)^{2} = (2)^{2} + (3\sqrt2)^{2} + 2(2)(3\sqrt2) }$

$\implies \boxed{(2+3\sqrt2)^{2} = 4 + 18 + 12\sqrt2 }$

Answer VerifiedVerified 88.5K+ Views Hint: We can use the property of vertically opposite angles are equal to find the unknown angles. Then we can add all the angles around the point and equate it to 360∘. Then we can solve for y to get the required solution. Complete step by step answer: We are given that ∠AOB=6y. Consider the line AD and EB. Then, ∠AOB and ∠EODare vertically opposite angles. We know that vertically opposite angles are equal. ⇒∠AOB=∠EOD=6y… (1) Consider the lines FC and EB. Then, ∠FOEand ∠BOC are vertically opposite angles and are equal. ⇒∠FOE=∠BOC We know that ∠FOE=4y, ⇒∠BOC=∠FOE=4y… (2) Now consider the lines AD and CF. Then, ∠FOAand ∠DOC are vertically opposite angles and are equal. ⇒∠FOA=∠DOC We know that ∠DOC=8y, ⇒∠FOA=∠DOC=8y… (3) Now we have the measures of all the angles around the point O. The sum of these angles will be 360∘ as it completes a full TURN around point O. ⇒∠AOB+∠BOC+∠COD+∠DOE+∠EOF+∠FOA=360∘ Using EQUATIONS (1), (2), and (3), we get, 6y+4y+8y+6y+4y+8y=360∘ ⇒36y=360∘ Dividing throughout with 36, we get, y=360∘36⇒y=10∘ Therefore, the required value of y is 10∘

Answer» Factorise the following: (x² – 2x)² – 23(x² – 2x) + 120 Step-by-step explanation: (x² – 2x)² – 23(x² – 2x) + 120 a = (x² – 2x) a² – 23a + 120 a² - 15a - 8a + 120 a(a - 15) - 8(a - 15) (a - 15) (a - 8) a = 15 or 8 x² - 2x = 15 or x² - 2x = 8 x² - 2x - 15 = 0 or x² - 2x - 8 = 0 (x - 5)(x + 3) = 0 or (x - 4) (x + 2) = 0 So the final answer is (x - 5) (x + 3) (x - 4) (x + 2) = 0

Factorise the following: (x² – 2x)² – 23(x² – 2x) + 120

Step-by-step explanation:

(x² – 2x)² – 23(x² – 2x) + 120

a = (x² – 2x)

a² – 23a + 120

a² - 15a - 8a + 120

a(a - 15) - 8(a - 15)

(a - 15) (a - 8)

a = 15 or 8

x² - 2x = 15 or x² - 2x = 8

x² - 2x - 15 = 0 or x² - 2x - 8 = 0

(x - 5)(x + 3) = 0 or (x - 4) (x + 2) = 0

So the final answer is

(x - 5) (x + 3) (x - 4) (x + 2) = 0
