Question

I am really frustrated-no one seems to want to help--Again the problem is v(x)=x^3-5x^2-2x+24. The depth is x+2. I am needing to know the linear expressions with integer co-efficients for the other dimensions. AND if the depth of the chest is 75 feet, what are the other dimensions? Please provide the answers and show all work as I am TOTALLY CONFUSED

Answer 1

V(x) is some function that represents the volume I presume?

Answer 2

the volume of you box, like any, is\[V=\ell wh\]only in this case the catch is that the length, width, and height are all given by polynomials

noone wants to help you out?

Answer 4

we know that\[h=x+2\]so we can then figure that\[\frac Vh={x^3-5x^2-2x+24\over x+2}=lw\]doing the polynomial ling division will get you a quadratic expression, which I'm betting can be factored

Answer 5

amistre64 I had two people but they had to go-I am really stumped here.

Answer 6

ok I am one
do you understand what I just said?

Answer 7

Turing Test-I do understand what you are saying-you were not one of the two who were helping on this particular problem earlier

Answer 8

I know that
here is a different explanation
do you prefer that I continue on your other thread from where the others left off?

Answer 9

if you do understand what I;m saying, use polynomial long division to get an expression for \[\frac Vh\]

Answer 10

thanks so much

Answer 11

..or synthetic division if you know it

Answer 12

once you have simplified \[\frac Vh\] you will be left with a quadratic that can be factored

Answer 13

Thanks for helping out I really do appreciate it

Answer 14

you are welcome, but I'd like to know that you are getting the right answer...
did you try the division?
