What is the area of this rectangle?

• 48

• $8x^2+14x+6$

• $8x^2+x+5$

• $2x^2+6x+8$

Factor Completely:

x⁴ - 81

• (x² + 9)(x² - 9)

• (x² - 9)(x² - 9)

• (x² + 9)(x - 3)(x + 3)

• (x - 3)(x + 3)(x - 3)(x + 3)

Four expressions are shown below.

I 2(2x² - 2x - 60)

II 4(x² - x - 30)

III 4(x + 6)(x -5)

IV 4x(x - 1) - 120

The expression 4x² - 4x - 120 is equivalent to

• I and II, only

• II and IV, only

• I, II, and IV

• II, III, and IV
