Question

Write a polynomial that represents the volume of a rectangular prism

the length is (4x-3) width is (x+1) and the height is (x+2)

Answer 1

Explanation:

volume=length×width×height

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

=(4x-3)[x²+2x+x+2]

=(4x-3)(x²+3x+2)

=4x(x²+3x+2)-3(x²+3x+2)

=4x³+12x²+8x-3x²-9x-6

=4x³+9x²-x-6
