If you purchase a Costco membership for $60 a year you can buy gas for $1.86 a gallon. If you don't purchase the membership you would have to pay on average $2.40 a gallon. What are the equations from the situation above?

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363

i think the answer is a.( -3, -1 )
