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.
