If a storm window has an area of 315 square inches, which equation can be used to find the dimensions when the window is 6 inches higher than it is wide (x represents height)?

Let x represents the height of the window

So width of the window will be (x-6)

Area of the storm = (h )(w)

315 = x(x-6)

315 = - 6x

- 6x - 315 = 0

Factors of the above equation will be

(x - 21)(x +15) = 0

x - 21 = 0 ⇒ x = 21 in

x + 15 = 0 ⇒ x = -15 in

We can not consider negative value as height never be negative.

So height = 21 in

Width = x - 6 = 21 - 6 = 15 in

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
