Answer:

Step-by-step explanation:
we are give f(x) and g(xl

combine like terms and it is done.
Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15
the three angles make a sum of 180: x+4x +5x+15=180
10x=165
x=16.5
the second angle is 4x=4*16.5=66
Answer:
12. 18g+80
13. 13x+13
14. 17s
15. 3t
Step-by-step explanation:
On each you just combine the like terms and simplify the equations.
(Add/subtract all of the common numbers)
