Answer:

Step-by-step explanation:
<u>Compound Interest</u>
This is a well-know problem were we want to calculate the regular payment R needed to pay a principal P in n periods with a known rate of interest i.
The present value PV or the principal can be calculated with

Solving for R

Where Fa is computed by

We'll use the provided values but we need to convert them first to monthly payments




Thus, each payment is


6x^2 + x - 15 = 6x^2 - 9x + 10x - 15 = 3x(2x - 3) + 5(2x - 3) = (3x + 5)(2x - 3)
Therefore, the other factor is 3x + 5.
The common ratio is -5, note that each value is the previous value multiplied by -5.
Any transformation involving change of scale will not result in a congruent figure. Rotations and reflections and translations maintain congruence.
