Answer:−2x^3+8x^2−4x
Step-by-step explanation:
Equation:-2x(x2-4x+2)
=(−2x)(x^2+−4x+2)
=(−2x)(x^2)+(−2x)(−4x)+(−2x)(2)
=-2x^3+8x^2-4x
Answer:
Wilma has $12.
Step-by-step explanation:
Since we don't know how many hours she worked, we know that Wilma earned 9x dollars at her job. Then she spends $15, so we can just subtract 15 from 9x.

that’ll give you 400 students
if you check
400*0.15=60
So its correct
