Quadratics Area

What is the area of this rectangle?

• 10x-4

• 25x²-20x

• 25x² - 20

• 20x - 8

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

The equation 2x²-5x=-12 is rewritten in the form of 2(x-p)²+q=0.  What is the value of q?

• 167/16

• 71/8

• 25/8

• 25/16

Which of the following represents a quadratic function?

• 5 and 16

(x+10)(x-10)

• x² - 100

• x² + 100

• x² + 20x - 100

• x² - 20x + 100
