Step-by-step explanation:

15 - c = 6
15 - 6 = c
9 = c
c = 9
Answer:
D.
Step-by-step explanation:
The formula is Sum(n) = (n -2) 180.
Find the slope first by doing (6+2)/(4-3)=8/1 or just 8. Next use a set of coordinates into the equation so 6=8(4)+b then solve so 6=32+b next subtract 32 from both sides which would equal -24=b. Then plug it all into the equation so y=8x-24
