The volume of the prism given its dimensions is equal to 160 cubic units.

<h3>What is the volume of the prism?</h3>

The given prism is made up of two prisms. The volume of the prism is the volume of the two shapes.

  • One of the prisms have the dimensions: 4 x 4 x 5.

Volume = 80

  • The other prism has the dimensions: 8 x 2 x 5.

Volume = 80

Volume of the prism = 80 x 2 = 160 cubic units.

I need help with this math question ill give brainliest plus free points
Mandarinka [93]

Answer:

The answer is C) -2 and 6

Step-by-step explanation:

x+4 / -3x^2 + 12x + 36

= x + 4 / -3 ( x^2 - 4x - 12)  

= x - 4 / -3(x - 6)(x + 2)

the excluded values make the denominator = 0  

so the answer is -2and 6
