Answer:
I think it's rational number
Answer C : 3x^2+7xy-2y^2
equivalent to the following expression


Combine like terms

2x^2 + x^2 is 3x^2
4xy+3xy is 7xy
-y^2-y^2 is -2y^2
So expression becomes

Answer C is correct
Here we are give the value for π and Diameter of the circle fence
π=3.14
Diameter = 16
Radius = Diameter/2
2πr = 2(3.14)(8)
Circumference = 50.27
Now to fine the square fence length so we do 16*4 = 64
64-50.27 = 13.73 in
Therefore, the square fence is 13.73 inches longer than the circle fence
