Apicture is 5 inches by 7 inches. there is a frame around the picture that is of uniform width. the area of the frame and the picture combined is 72 in2. how wide is the picture frame? write an equation that you would use to solve for x, the width of the picture frame. a) (5 + x)(7 + x) = 72 b) (5 - x)(7 - x) = 72 c) (5 + 2x)(7 + 2x) = 72 d) (5 - 2x)(7 - 2x) = 72
