The polynomial x 3 + 5x 2 57x 189 expresses the volume, in cubic inches, of a shipping box, and the width is (x+3) in. If the width of the box is 15 in., what are the other two dimensions? ( Hint: The height is greater than the depth.)

Best ResponseYou've already chosen the best response.0maybe polynomial long division will work here. Divide your polynomial by x+3 maybe.

Best ResponseYou've already chosen the best response.0because usually u have to factor. And you can take x+3 as a hint that it is one of the factors.

Best ResponseYou've already chosen the best response.0This is the factor that i figured out (x+3)(x−7)(x+9)

Best ResponseYou've already chosen the best response.0here is how i picture it in my head You are given x+3. U will need 2 other similar expressions to get a volume call them x+a x+b x+3 < given And together they form (x+a) * (x+b) * (x+3) = Volume height*depth* width = volume

Best ResponseYou've already chosen the best response.0width = 15 so you are told x+3=15 x=153 x=12 therefor x = 12 Plug it in :)
