Answer:Input : A = 12, B = 8
Output : X = 2, Y = 10
Input : A = 12, B = 9
Output : -1
Step-by-step explanation:

has y = 0 as a solution.
Selection B is appropriate.
I suspect this is what you mean, if let me know
2x(3)^2+x(2)^2
2(3)(9)+3(4)
54+12=66
A=P(1+r%)ⁿ , where P is the initial capital, r, the interest rate and n, the # years
A = 2000(1+0.13)³
A = 2000(1.13)³
A = 2,885.79
