Answer:
x = 5 inches
Explanation:
Given that,
The area of a rectangle = 39 inch²
The sides of the rectangle are (x-2) and (x+8).
The area of a rectangle is given by :
A = lb
So,
[tex]39=(x-2)(x+8)\\\\x^2+8x-2x-16=39\\\\x^2+8x-2x=55\\\\x=5\ in\ and\ x=-11\ in[/tex]
So, the value of x is equal to 5 inches.
