I REALLY NEED HELP! WILL MARK BRAINIEST!! follow up questions in the comments An office copier has an initial price of $2,100. A service contract costs $200 for the first year and increases $30 per year thereafter. It can be shown that the total cost of the copier after n years is given by C(n)=2,100+185n+15n^2.
The average cost per year for n years is given by b. C(n)=C(n)/n

1. Find the rational function of b. C(n)=C(n)/n

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
