(x-4)^2=36
take square roots,
± (x-4) =6
=>
x-4=6 => x=10
-(x-4)=6 => x-4 = -6 => x=-2
C.) infinitely many solutions.
Given the equation, x - 2(x -6) = -x + 12:
x - 2(x -6) = -x + 12
Distribute -2 into the terms inside the parenthesis:
x - 2(x -6) = -x + 12
x - 2x + 12 = -x + 12
Combine like terms:
-x + 12 = - x + 12
Subtract 12 from both sides:
-x + 12 - 12 = - x + 12 - 12
- x = - x
Add x to both sides:
- x + x = - x + x
0 = 0 (true statement).
This means that any value of x will satisfy the equation, thereby making it infinitely many solutions.

Hope this helps.
Apply the Pyth. Theorem:
c^2 = 3^2 + 7^2, or c^2 = 9 + 49 = 58. Thus, c = sqrt(58).
