A Dodecagon has 12 sides.
Start with this:
225+75-30
The +75 is the 75 points gained, the - 30 is the 30 points lost, and the 225 is her current points.
225 + 75 is 300,
300 - 30 is 270.
Anna finishes off with 270 points.
Maya wins the competition.

Just replace n with -2n, like this:
g(-2n)=-2n-4.
Divide by a power of ten to make the number in between 0 and 10. In this case, this is 8.97, and 10^8. Just multily them together.
8.97*10^8
This will be put into a fraction, like this:
15/80
From here, use long division. This would be easy to demonstrate if I had some paper, but I'll just show you the answer:
1580=316=0.1875
From here, round to the nearest hundreth.
0.1875-->0.19

First, input your variables:
3-2*4-(-4)
multiplication first:
3-8-(-4)
Now solve:
-5+4
-1
