The cable company is using stratified sampling
Tried my best to plot it:)
Answer:
The answer is -15.75 because 4= -16= -79 you have to turn 16 positive so add 16 to -79 to get -63 then divide by 4 to get the answer -15.75.
the answer was 5mx^2-8ax+x^2+3a
let's show your
(5m+1)x^2-8ax+3a
distribute
(5m)(x^2)+(1)(x^2)-8ax+3a
5mx^2+x^2-8ax+3a
answer was 5mx^2-8ax+x^2+3a
hope this helps
