Domain is the x

Answer:
The formula to find the perimeter of a rectangle is 2*length + 2*width
2(2x+1)+2(x^2+2x-1)
First we want to distribute the 2 through both the length and the width
(4x+2) + (2x^2+4x-2)
After we distributed the 2 through like we did up above, we now want to add them together to find the perimeter.
We want to combine all like terms
2x^2, doesn't combine with anything so we leave it the same
4x+4x=8x, add the coefficients and leave the variable
2-2=0, we just leave that out, don't do anything with it
What we have left is:
2x^2+8x,
Which would be C), if the answer is 2x to the second power+8x,
Hope this helps ;)
