Roxanne is comparing the monthly payments for a new car at two different car dealerships. Dealership A: The car costs $30,000, and the loan has an annual interest rate of 4.8%.
Dealership B: The car costs $29,800, and the loan has an annual interest rate of 5.4%.

Use the formula to determine the monthly payment for each dealership.

Assume that both interest rates are compounded monthly, there is no down payment, and each loan is for 60 months.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
