71. suppose that you currently have one credit card with a balance of $10,000 at an annual rate of 24.00% interest. you have stopped adding any additional charges to this card and are determined to pay off the balance. you have worked out the formulabn = b0r n − r(1 + r+r2 ++ r n−1), where b0 is the initial balance, bn is the balance after you have maden payments, r= 1 + i, wherei is the monthly interest rate, and r is the amount you are planning to pay each month.
c. how long does it take to pay off this debt if you can afford to pay a constant $250 per month? give the
answer in years and months.

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
