Answer:

Step-by-step explanation:
After x=2, we see that the change in y over the change in x is positive since both variables increase with each other, so

Answer:6
Step-by-step explanation:2+4
Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
