3x+19
Step-by-step explanation:
2x are like terms and 4 and 15 are like terms so you add them together
The n two number are n and n+7. The two numbers are relatively prime because 7 is prime and doesn't divide 60. So we get n(n+7)=60. Guess and check tells us the two numbers are 5 and 12.
F(-1)= 4*7(-1) = 4*-7 = -28
F(2)= 4*7(2) = 4*14 = 56
