A. (x+2) (x2 +x+2) + 2(x3 + x2)
hram777 [196]

Answer:

3x³ + 5x² + 4x + 4

Step-by-step explanation:

Given

(x + 2)(x² + x + 2) + 2(x³ + x²)

To expand the product, each term in the second factor is multiplied by each term in the first factor, that is

x(x² + x + 2) + 2(x² + x + 2) + 2(x³ + x²) ← distribute the parenthesis

= x³ + x² + 2x + 2x² + 2x + 4 + 2x³ + 2x² ← collect like terms

= 3x³ + 5x² + 4x + 4

Ede4ka [16]

Answer:

D

Step-by-step explanation:

2 sin²x=sin x

2 sin² x-sin x=0

sin x(2 sin x-1)=0

sin x=0

x=0,π

2 sin x-1=0

SSSSS [86.1K]

Answer: There are 12 pairs of tennis shoes.

Step-by-step explanation:

Since we have given that

For each pair of tennis shoes , she owns 4 pairs of flip flops,

so their ratio will be 1:4

Let the number of tennis shoes be x

Let the number of flip flops be 4x

According to question,

4x-x=9

3x=9

x=\frac{9}{3}

x=3

So, the number of pairs of tennis shoes is given by

4x=4\times 3=12

Hence, there are 12 pairs of tennis shoes.
