Question

The volume of a rectangular prism is represented by the function x3 + 9x2 + 6x - 16. The length of the box is x + 2 while the height is x + 8. Find the expression representing the width of the box. (2 points)
Answer

x - 4

x - 1

x + 1

x + 4

Answer 1

The width is x-1
You first multiply (x+2) by (x+8) and you find (x2+10x+16)
Then divide (x3+9x2+6x-16) by (x2+10x+16) to get x-1

Answer 2

you copied that from what I said before

Answer 3

haha just kidding, but thats exactly what i said before

Answer 4

You can do what you did in the previous example, but notice that when you multiply
(x + 2) by (x + 8) using FOIL, the last term of the product will be 16.
When you multiply that by another binomial (x + a), the result will have to have a last term of -16. That seems to show that the factor you are looking for is (x - 1)

Answer 5

my answer is b
