Answer:
The Answer is D 
Step-by-step explanation:
All you do is add both equations 3^x+10x+2x-4 
then you add the like varibles which is 10x+2x=12x 
So, the answer is 3^x+12x-4

It's forming a circle so we know that together it's going to add up to 360. #1 is 66 because angle A trough E is straight and we have 90 on angle ACF and it's vertical to angle FCG. #2 is 125 because angle ACB is 24 because it's vertical to angle GCE. #3 is 114 because 90 and 24 is 114. #4 is 156 because 66 and 90 equal 156.
1. FCG = 66
2. BCD = 125
3. FCB = 114
4. ACG = 156
