P- (-1,7) Q-(2,7) R-(7,-3) S-(-4,-4)
start inside the square root, replace X with -7.
-7 + 11 = 4
The number 4 comes out of the square root as 2.
Now there's a minus factor out there. Let's multiply this negative factor by 2 and get -2.
Now let's add -2 and -3.
Our output is -5.
5+3a = 3-2a
So
5a = -2
a=-2/5=-0.4
Equal is the with the 38+
