Question 9 of 20 : select the best answer for the question. 9. –2x(–3x 2y)(2y) = ? a. 12x3y2 b. –3xy2 c. 3xy2 d. –12x3y2

For this case we must find the product of the following expression:

We take into account that:

To multiply powers of the same base, the same base is placed and the exponents are added:

Option A

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
