Question

How would you write an expression using a variable for the area and perimeter of a square with side 2x-9
NEED HELP ASAP

Answer 1

perimeter :
because there are four sides to a square and all sides are the same, the answer is 4(2x-9)
area:
area is basically length times width so the answer is (2x-9)(2x-9) or (2x-9)^2
