To solve this, you need to isolate/get the variable "r" by itself in the equation:
-1 = -3r + 2r Combine like terms(terms that have the same variable and power/exponent.) The only like terms you can combine are -3r and 2r
-1 = -r Divide -1 on both sides to get "r" by itself
(two negative signs cancel each other out and become positive)
1 = r or r = 1

Answer:
B) f(g(x)) = 15x² + 18
Step-by-step explanation:
Plug the entire equation of g(x) in for the x in f(x)
f(g(x)) = 5(3x² + 3) + 3
f(g(x)) = 15x² + 15 + 3
f(g(x)) = 15x² + 18
