Area is 96 length is 4x+8 width is x find x

Answer

Step-by-step explanation:

The area would be length times width. x (4x+8) = 96

4x^2+8x = 96

4x^2+8x-96=0. We need to factor.

It would be factored to (4x-16) (x+6) = 0

x would be - 6 (x+6=0)

or x would be 4 (4x-16=0)

Why would the width be negative?! So the answer is 4
