Calista is painting a new picture. The height (H) of the frame is 2 inches taller than it is wide (W). If the area of her picture is 35 in², which equation represents the area?

• 35 = (W)(2+W)

• 35 = (H)(2+H)

• W = 35 + 2

• H = 35 + 2

Calista is painting a new picture. The following equation represents the area. 35 = (W)(2 + W). Which equation is equivilant?

• W² - 2W - 35 = 0

• W² + 2W - 35 = 0

• W² + 2W + 35 = 0

• W² - 2W + 35 = 0
