The answer is no solution
Step-by-step explanation:
The equation is
and 
Subtracting these two equations, we get,

Thus,
is not possible.
Hence, the system of equations have no solutions.
There are different formulas for each different shape.
Answer:
x=8 y=4
Step-by-step explanation:
x=12-y
12-y-y=4
-2y=-8
y=4
x=12-y
x=12-4
x=8
Answer:
this is not the answer but it might help you find the answer
Step-by-step explanation:
The area of a regular decagon can be calculated using the formula for finding the area of a general regular polygon. Area of a Regular Polygon = 12 x Perimeter x Apothem. The diagram of a regular decagon ABCDEFGHIJ is given above.
