The volume of a rectangular prism is #3x^3+34x^2+72x-64#, if the height is x+4, what is the area of the base of the prism?

Answer 1

#3x^2 +22x - 16# square units.

The formula for volume of a prism is #V = A_"base" * h#. Therefore,

#3x^3 + 34x^2 + 72x - 64 = (x + 4)A_"base"#

#A_"base" = (3x^3 + 34x^2 + 72x - 64)/(x+ 4)#

Use either synthetic or long division. I will use long division but either methods work.

Therefore, the quotient is #3x^2 + 22x - 16#. This means the area of the base is #3x^2 + 22x - 16# square units.

Hopefully this helps!

Answer 2

To find the area of the base of the prism, we need to divide the volume by the height.

Dividing the volume (3x^3 + 34x^2 + 72x - 64) by the height (x + 4), we get:

(3x^3 + 34x^2 + 72x - 64) / (x + 4)

Using polynomial long division or synthetic division, we can divide the polynomial to find the quotient:

Quotient = 3x^2 - 2x + 16

Therefore, the area of the base of the prism is 3x^2 - 2x + 16.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
