Step-by-step explanation:
X^3 + 3x^2...factor out x^2
x^2 (x + 3) <==
Subtract the right side and you have
x² -10x -6 -2x -1 = 0
x² -12x -7 = 0
This corresponds to the selection ...
C. x² -12x - 7 = 0
138.. cause there is 18 ones that makes one ten.. and 8 left over.. so then you will have 1 hundred, 3 tens, and 8 ones.
Answer:
