Answer:
Applying Quotient and power rule. Graphically, for x>0 both curves coincide.
Step-by-step explanation:
1) Firstly, by applying the Quotient and then the Power Rule, we have a subtraction of the argument and, finally the exponent turns to be the coefficient. As it follows:

2) Check the graph below to see this equivalence. to see x>0 they both coincide.
30
you have to do the math of 9x2=18 then you add 12 to your answer and your answer is 30
