fish tank's design specifies a length that is 8inches longer than the width. Height of the tank is to be 5inches longer than the width. Let w represent the width and write expression for the volume of the tank in terms of w.
(8+w)(5+w)
40+8w+5w+w^2
my answer is: w^2+13w+40
is that right?

Best ResponseYou've already chosen the best response.0so the answer is w(w^2+13w+40) or do i need to take w times everything inside the ()?

Best ResponseYou've already chosen the best response.0I'd either leave it as w(w+5)(w+8) or w^3 + 13w^2 + 40w Pick one of the other, don't get stuck in the middle.
