A photographer needs a frame for an 5 x 7 inch picture, such that the total area is 80 in^2. Calculate the width of the frame. (Note: The frame is the same width all the way around)

Which of the following quadratic equations would be used when solving this?

a.) 2x^2 + 12x = 45
b.) 4x^2 + 24x = 45
c.) 4x^2 + 12x = 45
d.) 2x^2 + 24 = 45
