Inverse Property of Addition
        
                    
             
        
        
        
The answer is x=20. You isolate the square root. Eliminate the radical on the left handside. And then solve it!

Answer: A) parabola</h3>
Some degenerate parabola cases form a single straight line, while other cases form one pair of parallel lines. 
A degenerate hyperbola forms two lines that intersect at the vertex of the cone. We can rule out choice B.
A degenerate circle is a single point, so we can rule out choice C.
A degenerate ellipse is also a single point. Any circle is an ellipse (but not the other way around). We can rule out choice D.
 
        
             
        
        
        
104 Because 100*4 = 400 and 4*4 = 16 so add together and get 416
