Rotation and reflection are instances of transformation
See attachment for the new position of ![\triangle ABC](https://tex.z-dn.net/?f=%5Ctriangle%20ABC)
From the question, we have:
![A = (-1,1)](https://tex.z-dn.net/?f=A%20%3D%20%28-1%2C1%29)
![C = (-2,4)](https://tex.z-dn.net/?f=C%20%3D%20%28-2%2C4%29)
The rule of 90 degrees clockwise rotation is:
![(x,y) \to (y,-x)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%5Cto%20%28y%2C-x%29)
Using the above transformation, the new points would be
![A' = (1,1)](https://tex.z-dn.net/?f=A%27%20%3D%20%281%2C1%29)
![B' =(3,3)](https://tex.z-dn.net/?f=B%27%20%3D%283%2C3%29)
![C' = (4,2)](https://tex.z-dn.net/?f=C%27%20%3D%20%284%2C2%29)
The next transformation is reflection over the x-axis
The rule of this transformation is:
![(x,y) \to (x,-y)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%5Cto%20%28x%2C-y%29)
So, the new points would be:
![A" = (1,-1)](https://tex.z-dn.net/?f=A%22%20%3D%20%281%2C-1%29)
![B" = (3,-3)](https://tex.z-dn.net/?f=B%22%20%3D%20%283%2C-3%29)
![C" = (4,-2)](https://tex.z-dn.net/?f=C%22%20%3D%20%284%2C-2%29)
See attachment for the new points

Step-by-step explanation:
So I dont really get the equation because its written confusingly but I will try my best.
1. √(2x+10) -6=2
2.√{2x+10}=8
3.√{2x+10}^2=8^2
4.2x+10=64
5.x=27
