Answer: 12x^3 + 19x^2 -27x -40
Step-by-step explanation:
Finding f(x) times g(x) is multiply the two polynomials
(4x+5)(3x^2 + 1x -8) Apply the distributive property twice to solve
4x ( 3x^2 + 1x -8)
12x^3 + 4x^2 - 32x
5(3x^2 + 1x -8)
15x^2 + 5x - 40
12x^3 + 4x^2 - 32x + 15x^2 + 5x -40 now combine like terms
12x^3 + 19x^2 -27x -40

And don’t know the options given for the bottom
Half the area is 6000.
let x be the width of the walk so the inner rectangle has a length of 150-2x and width 80-2x and hence its area is (150-2x)(80-2x) which is equal to 6000.
so now we have an equation in terms of x which reduces to a quadratic and we solve for x
