Question

i need help with just one question, and if i get it, ill be able to do the rest. Okay so its saying let height of a box be 4x+1, width be x-3, and length be 2x. Find the volume.
So what do i do? how do i start solving this? its polynomials

Answer 1

H=Hight

W=Width

L=Length

V=Volume

V=H*W*L

V=(4x+1)*(x-3)*2x

V=[4x*x + 1*x + 4x*(-3) +1*(-3)]*2x

V=(4x^2 +x -12x -3)*2x

V=(4x^2 -11x -3)*2x

V=4x^2*2x - 11x*2x -3*2x

V=8x^3 -22x^2 -6x

Answer 2

thank you so much.
