Answer:
800
Step-by-step explanation:
C. 5x+7=22 since diameter is equal to double the radius. radius=11 so diameter equals 22. then just make 5x+7 = to 22
A = P(1 +rt) where A is the total amount(principal and interest), r is the rate, and t is the time invested.
A = 5200[1 + .0736(4.5)]
A = 6922.24
note we had to change the rate to a decimal by dividing by 100
Also 54 months is equal to 4.5 years...you enter time in years.
