The answer is 2.26796 i am pretty sure
No because there are 2 of the same x values. There can be the same y values but not x.
Answer:
x=2
Step-by-step explanation:
3x - 9x + 7 - 3 = -8
Combine like terms
-6x +4 = -8
Subtract 4 from each side
-6x +4-4 = -8-4
-6x = -12
Divide each side by -6
-6x/-6 = -12/-6
x = 2
The polygon would have 18 sides. Hope this helps!
