Answer:
5x+12
Step-by-step explanation:
I think it is 1, 4, and 5
C/30 = 8/12
c/30 = 2/3
3c = 60
c = 60/3
c = 20
ANSWER

EXPLANATION
The given function is;

The constant term is 11.
The coefficient of the leading term is 5.
The factors of 11 are ±1,±11
The factors of 5 are ±1,±5
According to the Rational roots Theorem,
the potential roots are obtained by expressing the factors of the constant term over the coefficient of the leading term.
