Answer:
B. x=-6 or x=8
Step-by-step explanation:
To solve this, factor the equation x^2-2x-48. Since -48 is negative, one of the factors has to be negative and one has to be positive. Since the coefficient of x is -2, the factors have to sum to -2. Trying factors, we realize that (x-8)(x+6)=0 works. Solving, x-8=0 and x+6=0, or x=8 or x=-6.

Step-by-step explanation:
Answer: The credit card will paid off within 10 years, therefore the correct option is D.
