Question

if a storm window has an area of 315 square inches what are the dimensions if the window is 6 inches higher than it is wide ( x represents height)?

Answer 1

Hey there! The formula for area is area=l*w, l=w+6. Let's begin, 315=(w+6)(w), 315=w^2+6w, 0=w^2+6w-315, 0=(w+21)(w-15), w+21=0w-15=0, w=-21w=15. Therefore, we come up with a answer of w=15 and l=21.
