A = P + Prt
A = P/P + Prt/P
A = P(1 + rt)
A/P = P(1 + rt)/P
A/P = 1 + rt
A/P - 1 = 1 - 1 + rt
A/P - 1 = rt
(A/P - 1)/t = rt/t
(A/P - 1)/t = r
Thus r = (A/P - 1)/t.
The answer is a=9 because 14 minus 5 equals 9.
I think that x^2-9 (difference of 2 squares), 216x^3 +729 (sum of 2 cubes), and the other two are none
Not entirely sure
Answer:

Step-by-step explanation:
1. Find the Greatest Common Factor of the numerator and denominator.
The prime factors of 35 are <u>5</u>, 7, 35
The prime factors of 60 are 2, 3, 4, <u>5</u>, 6, 10, 12, 15, 20, 30, 60
The only common factor of 35 and 60 is 5.
2. Divide the numerator and denominator by the Greatest Common Factor.
