Area Quadratics

The length of a rectangle is (x + 9) and the width is (x + 5). What is the area of the rectangle as a quadratic equation?

• y = x² + 14x + 45

• y = x² + 9x + 45

• y = x² + 14x + 14

• y = x² + 20x

The length of a rectangle is 2 units more than the height.

Given the total area is 80, which equation is correct

• x(x+2) = 80

• x(x+2) = 40

• x+(x+2) = 80

• 2(x+(x+2)) = 80
