Required expression is x/9 - 7
Yes because 10^2+10^2=200
If you multiply a square root by itself it removes the root. Therefore making the statement 100+100=200; True
One solution because it only has one answer that can come out if those properties. If you add the -3 to -6 it will make it 6=12 -3x. Subtract the 12 it will be -6=-3x divide by -3 and x=2
