Which is an expression for the volume of the prism?(V = lwh ) A. x^2 + 4x - 5
B. x^2 + 6x + 5
C. 3x^2 + 12x - 15
D. 3x^2 + 18x + 15

C. 3x² + 12x - 15

Step-by-step explanation:

length (L) = x - 1

width (w) = x + 5

height (h) = 3

Volume (V)

= L * W * h

= ( x - 1) ( x + 5) 3

= 3 ( x² + 5x - x - 5)

= 3 ( x² + 4x - 5)

= 3x² + 12x - 15

Hope it will help :)

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
