Your original purchase price was $825.00 plus 7% sales tax. you enter into an agreement

where the interest (12.5% apr) is waived for the first 12 months provided you make the

required monthly payments; otherwise the interest is accrued from the date of purchase. you

miss the first payment due date. the late fee is $35.00. how much is the interést?

so, converting firstly the mixed fractions to improper fractions and then "adding".

he earned 78.75 in interest.

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
