Answer:

Multiply s(x) function and t(x) function together.  

(x-7)(4x^2-x+3) = 4x^3-28x^2-x^2+7x+3x-21 = 4x^3-29x^2+10x-21

<h3>Answer:  576 </h3>

============================================================

Check out the diagram below.

I've split the figure into 3 separate blocks. We calculate the volume of each block, then add up those volumes to get the final answer.

  • Block A = largest block on the left
  • Block B = middle block
  • Block C = smallest block on the right

So,

  • volume of block A = length*width*height = 6*6*8 = 288 ft^3
  • volume of block B = length*width*height = 6*6*5 = 180 ft^3
  • volume of block C = length*width*height = 6*6*3 = 108 ft^3

Therefore, the total volume we're working with is:

A+B+C = 288+180+108 = 576 cubic feet

The "cubic feet" or "ft^3" portion is already taken care of by your teacher, so you just need to type in the number itself.
