Question

Find the value of x if the area is 135 square inches

Answer 1

x=9

Explanation:

This equation, in my use, is more of a guess-and-check. I noticed 15 divides nicely into 135 and then punched that into my calculator. 135/15 = 9. And when you add 9 and 6 together, it makes 15. Therefore, x must equal 9.
