Answer:
5x^3+17x^2-35x-30
Step-by-step explanation:
First, multiply the length of the shaded region by the width.
(x^2+4x-10)(5x+3)
=5x^3+17x^2-35x-10
Then, find the area of the non-shaded region.
(3x)(2x-1)
=6x^2-3x
Finally, subtract the non-shaded region from the shaded region.
(5x^3+23x^2-38x-30)-(6x^2-3x)
=5x^3+17x^2-35x-30
