Find the volume of the given prism. round to the nearest tenth of necessary.

B.

Step-by-step explanation:

We have been given an image of a prism and we are asked to find the volume of our given prism.

We will use volume of rectangular prism formula to solve our given problem.

, where,

l = Length of prism,

w = Width of prism,

h = Height of prism.

Upon substituting our given values in above formula, we will get

Therefore, option B is the correct choice.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
