Question

if one side of a square measures (3x - 8)ft., find the area of the square show work

Answer 1

Answer:

$9x^{2}$-48x+64

Step-by-step explanation:

First, start off with what the area would look like with the equation plugged in.

$(3x-8)x^{2}$=area -----> (3x-8)(3x-8)

Second, multiply out the numbers in the ()s.

(3x-8)(3x-8) ---> (3x)(3x) = $9x^{2}$ --->(3x)(-8)=-24x----->(-8)(3x)=-24x------>(-8)(-8) = 64

Finally, you combine like terms and you have your answer.

$9x^{2}$-24x-24x+64 -----> $9x^{2}$-48x+64

Hoped this helped!
