(x+2)(x+8)(x+k)=x^3+9x^2+6x-16
(x^2+10x+16)(x+k)=x^3+9x^2+6x-16
x^3+10x^2+16x+kx^2+10kx+16k=x^3+9x^2+6x-16
kx^2+10kx+16k=-x^2-10x-16
k(x^2+10x+16)=-x^2-10x-16
k=(-x^2-10x-16)/(x^2+10x+16)
k=-1
so the width is (x-1)
Answer:
15
Step-by-step explanation:
4(5x + 3) - 4x
4*5x = 20x
4 * 3 = 12
20x and 4x are like terms,so 20x - 4x=16x
12 doesn’t have anything to go with,so it just stays
16x + 12 (B is the correct answer)
