You need to first make everything positive:
x^2=36
Then you need to get the square root of each side:
x=6 or -6
Hope this helps :)
It is D.
Reason. 3^2 is 9, 4^2 is 16.
16+9= 25
The square root of 25 is 5.
Therefore it is D.
I think this would be 4≥X<span>>-8

The answer would be D. Mice and Rabbits. Hope it helps! :)
