Group Title
Zach wrote the formula w(w1)(5w + 4) for the volume of a rectangular prism he is designing, with width w, which is always has a positive value greater than 1. Find the product and then classify this polynomial by degree and by number of terms.
Choices:)
A.) 5w^5  w^4  4w^3; quintic trinomial
B.) 20w^2; quadratic monomial
C.) 5w^3  w^2  4w; cubic trinomial
D.) 5w^4  w^3  4w^2; quartic trinomial

Well, first I would factor the (w1)(5w+4) and the multiple the result by the remaining w. See which answer choice you get.

When you factor (w1)(5w+4) without multiplying the remaining with the w do you get 5w^2  4w + 5w + 4

Not quite. The first and last terms are correct but you need to: (1)(5w) and (4)(w) In other words, look at you signs. Also, you should add those two together because they share a common variable (w to the 1st power). Now multiply that equation by w and you should see your answer appear.

is the answer C ? 5w^3  w^2  4w; cubic trinomial

I dunno. Can we give proof for why?

Because that's what I got when I figured out the problem, I was just making sure it's right.
