Answer:
x-3
Step-by-step explanation:
(x+5)(x-1)(height)=x3+x2-17x+15
x2+5x-1x-5(h)=x2+4x-5
so what times x2+4x-5 will equal the volume
look at the constant -5 and think what will multiply with that to get 15 so -3 right so then check the rest of it by doing (x2+4x-5)(x-3) =x3−3x2+4x2−12x−5x+15
=x3+x2−17x+15 so the answer is x-3
Hope this helps! :)
