9.	Two factors of ax^3 + bx^2+ cx - 2 are (x + 1) and (2x +1). The remainder when theexpression is divided by x + 2 is -12. What is the third factor of the expression?Please solve this
Answer» Answer: Step-by-step explanation:You have asked similar questions. You should know by now that x+1 or x-1 MUST be a factor if it can be done with integers at all (because the coefficients must DIVIDE leading and trailing coefficients of your polynomial). Also in that case x = 1 or x = -1 should be roots of the polynomial. And yes, x = -1 is a root. So x^3 + 2X^2 + 2x + 1 = (x+1)(x^2 + ?x + 1) and you should very easily find the value of ? that MAKES the other terms of the PRODUCT work out. Now you have a quadratic to factor which is not possible with integers. But you can find the factors by solving a quadratic equation. Hint:

Answer» ☆ $\LARGE{\bf{\underline{\underline{\ Solution}}}}$ ☆ Ratio of the angles of triangle = 5:6:7 → Let : FIRST ANGLE = 5x Second Angle = 6x Third Angle = 7X → ACCORDING to the angle sum property : 5x + 6x + 7x = 180 ⇒ 11x + 7x = 180 ⇒ 18x = 180 ⇒ x = 180/18 ⇒ x = 10 → THEREFORE, the angles will be : First angle = 5x = 5 × 10 = 50° Second angle = 6x = 6 × 10 = 60° Third angle = 7x = 7 × 10 = 70°

23.

The angle of a triangle are in the ratio 5:6:7what are the angle?

Answer»

☆ $\LARGE{\bf{\underline{\underline{\ Solution}}}}$ ☆

Ratio of the angles of triangle = 5:6:7

→ Let :

FIRST ANGLE = 5x

Second Angle = 6x

Third Angle = 7X

→ ACCORDING to the angle sum property :

5x + 6x + 7x = 180

⇒ 11x + 7x = 180

⇒ 18x = 180

⇒ x = 180/18

⇒ x = 10

→ THEREFORE, the angles will be :

First angle = 5x = 5 × 10 = 50°

Second angle = 6x = 6 × 10 = 60°

Third angle = 7x = 7 × 10 = 70°

27.	1. Shikha bought 12 m 50 cm cloth of one kind and 5.17 m 25 cm cloth of another kind. Find the totallength of cloth bought by Shikha.
Answer» Answer: Step-by-step explanation: Answer:Length of cloth = 12 m 50 cm Length of cloth another = 17 m 25 cm As we know. For adding TWO numbers their unit must be the same. So MAKING length in meter: 3m+20cm=3\:m+\frac{20}{100}m =3\:m+0.2m =3.2m and 2m+5cm=2\:m+\frac{5}{100}m =2\:m+0.05m =2.05m Now, Total Length of the cloth = 3.2 m + 2.05 m = 5.25 m Hence Sarikha BOUGHT cloth with a length of 5.25 m

1. Shikha bought 12 m 50 cm cloth of one kind and 5.17 m 25 cm cloth of another kind. Find the totallength of cloth bought by Shikha.

Answer»

Answer:

Step-by-step explanation:

Answer:Length of cloth = 12 m 50 cm

Length of cloth another = 17 m 25 cm

As we know.

For adding TWO numbers their unit must be the same.

So MAKING length in meter:

3m+20cm=3\:m+\frac{20}{100}m

=3\:m+0.2m

=3.2m

and

2m+5cm=2\:m+\frac{5}{100}m

=2\:m+0.05m

=2.05m

Now,

Total Length of the cloth = 3.2 m + 2.05 m

= 5.25 m

Hence Sarikha BOUGHT cloth with a length of 5.25 m

My high school teacher also taught that the x term should be positive.

Write an equation in standard form for the line which contains (2,6)and (1,2)

Answer»

Answer:

Ax + By = C

As you can see, the x and y terms are on the same side of the equation. Also required is that the A and B are whole numbers. My high school teacher also taught that the x term should be positive.

So, we’ll achieve all three:

First, find the slope of the line containing the given points: (y2-y1)/(x2-x1) for (1, -2), (4,6):

(6- -2)/(4- 1) = 8/3 = m

use that slope and either point (I use (4, 6)) in either point slope or slope intercept equation.

I use point slope:

y - 6 = (8/3)(x - 4)

y - 6 = (8/3)x - (32/3)

clear fractions by multiplying by the lcd of 3:

3y - 18 = 8x - 32

subtract 3y from both sides, add 32 to both sides.

result:

8x-3y = 14. STANDARD FORM of the equation, which fulfills all three criteria I set out above.
