U times any number by 3 and see witch ones the closest
27x3=81 that's what I think and that's the closest
The answer is A. A, D the reason being, is because polygons have sides C, and B have no sides so we can eliminate those immediately.
-6 +8x = -38
8x = -32
x = -4
I did this by first adding 6 to both sides to get 8x by itself. I then divided by 8 to get x by itself. I remembered to use the - - + rule (Two negatives make a positive, a positive and a negative make a negative). Hope this helps!
