Carolyn is planning a community garden she would like the length of the garden to be 4 feet more than its width. Carolyn wants to find out how much it would cost to buy fencing to put around the entire garden. What expression can she use to represent the perimeter of the garden?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
