The width of a rectangular prism is five less than the length, and the height of the prism is twice the length. Let x represent the length of the prism.
For what values of x will the volume of the rectangular prism be 500 cubic units or greater?
O x < 8.5 units
O x > 8.5 units
O XS 8.5 units
O x 28.5 units

your answer would be b

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
