Question 201718
This is a word problem and I can't use the perfect square I have to use the quadratic equation
5x7 photo that I have to put on a piece of paper
the area of the mat should equal that of the picture. I have to determine the proper l and width.
5x7 = 35 sp" 
(5 + 2x)(7+2x) = 35
Actually, the total area of the paper has to be 70 sq inches, since 35 will be covered by the photo.
(2x+5)*(2x+7) = 70
4x^2 + 24x - 35 = 0
x = 1.213 inches
