The area of a rectangle is (y^2-8y+15) square inches. which expression represents a possible length? a. (y+5) b. (y-15) c. (y-2) d. (y-3)

D. (y-3)
I'm assuming that they want you to find the factors of the quadratic expression, which are (y-5)(y-3). (y-5) isn't up there, so (y-3) is the only solution that's really possible.
