A 5 inch by 7 inch picture is placed in a frame that creates a uniform border of x inches around the picture. The area of the entire frame(including where the picture is placed) is equal to 120 square inches. Write an equation in terms of x that models the situation.
+37162 (2x+7)(2x+5) = 120 would be one way.....you can multiply the l side to get
4x2 +24x - 85 = 0
