So you’ll take $11.50-$4.75=$6.75 then you’ll divide this answer by 3 6.75/3=2.25 so it was $2.25 per movie to rent
the answer to this question is y=2x.
The only way to do this one is by long division which I can't figure out how to show here. There are some great examples online if you google long division with polynomials.
The answer is 3x^2+3x+3 with a remainder of 5x+6 who's is usually shown as (5x+6)/2x^2 +2x+4 which was the divisor g(x).
