• 2 / (x+4) + 9 / [5(x+4)] = 2(5) / [5(x+4)] + 9 / [5(x+4)] = (10+9) / [5(x+4)] = 19 / [5(x+4)]

• 1. H+R=20, so H = 20-R. 2. V=pi R^2 H = pi*R^2 *(20-R) = pi(20R^2 - R^3) 3. dV/dR = pi(40R - 3R^2). dV/dR = 0 if 40R = 3R^2. Then R=0 or R=40/3. R=0 provides the minimum volume of zero. R=40/3 provides the maximum volume o…

• 1. w(w-1)(3w+2) = w(3w^2 +2w - 3w - 2) = w(3w^2 -w -2) = 3w^3 - w^2 - 2w There are three terms, and the degree is three (this is the highest exponent on any one of the terms). 2. There are 7 different choices for first, and then there wil…
