Answer:
8-2x+y
Step-by-step explanation:
8-2x+y
Answer with explanation:
Sum of interior angles of any polygon having , n sides = (n-2)×180°
It is given that, sum of interior of any polygon =300°
A.T.Q
→ (n-2)×180=300
→Means that ,number of sides of the polygon is a fraction,which is Impossible.
Hence, we can conclude that,it is Impossible to have, 300 degrees in the sum of the interior angles of a polygon.
Option C: Never
Y = -1/2x + 4
X + 2y = -8
Replace y in the second equation with the first one:
X + 2(-1/2x +4)=-8
Simplify:
X -X +8 = -8
Simplify:
8 = -8
Subtract 8 from both sides:
0 = -16
This is a false statement, so there are no solutions.
