Answer:
D
Step-by-step explanation:
The question continues with these options:
a. x3 − 8x2 − 11x + 20
b. x3 − x2 + 22x + 40
c. x3 + x2 − 22x − 40
d. x3 + 8x2 + 11x − 20
A cubic in equation (x+5)(x+4)(x-1) or on a graph that crosses at -5, -4, and 1. Multiply the factors out to find the equation.
You should add them up both of the sides

If you would like to solve the system of equations 2r + 2s = 50 and 2r - s = 17, you can do this using the following steps:
<span>2r + 2s = 50
2r - s = 17 ... 2r = 17 + s
</span>____________
<span>2r + 2s = 50
</span>17 + s + 2s = 50
17 + 3s = 50
3s = 50 - 17
3s = 33
s = 33/3
s = 11
<span>2r = 17 + s = 17 + 11 = 28
</span>2r = 28
r = 28/2
r = 14
(r, s) = (14, 11)
The correct result would be <span>d. r = 14, s = 11.</span>
