The answer would be 5227. If you subtract what is in parenthesis first and then multiply it that should be your answer.
The value of X is how peaches bought
The value of Y is how much you pay
The first one is 23.430, I don't have time to help with the second part of the question, but good luck! :)
Simplify whatever is in the parenthesis:
(5×^2-4x-1) and <span>(4x^2-4)
after that subtract the numbers you got from both </span>parenthesis after simplifying
