Answer: x = √58
Decimal: 7.6157710 (Not Rounded)
Explanation: Using pythagorean theorem because it’s used for right triangle when mostly trying to find the hypotenuse. 
3^2 + 7^ = c^2
        
             
        
        
        
Answer:
The center is (-3,2) and the radius is r=2
Step-by-step explanation:
The general equation of the given circle is 

Add the square of half the coefficient of the linear terms to both sides of the equation to obtain;



The quadratic trinomials in x and y on the left side of the equations are perfect squares.
We factor to obtain;


Comparing to:

The center is (-3,2) and the radius is r=2
