Chris has a credit card with a balance of $5,400 and an APR of 22.5%. With the monthly payments he has been making, Chris would be able to pay off his credit card in 18 months. After receiving a promotional offer in the mail, Chris decides to transfer his balance to a new credit card with a 15% "introductory" APR for the first 12 months. After 12 months, the APR increases to 23%. How much will Chris save in finance charges (interest) if he pays off the credit card before the introductory APR expires? Please explain how you got it thank you.

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
