Consider this option:
1. rule: Circle is the locus of the points which are on the same distance from the given point. Common view of the equation is: (x-a)²+(y-b)²=r², where r - the distance from the given point to the described locus, a&b - coordinates of the given point.
2. using item 1:
(x+2)²+(y-1)²=3² or (x+2)²+(y-1)²=9.
$x=3$ I think that’s it... try that
If the mug was traced in the center of the paper, she could fold the paper in half vertically and horizontally to find the center point of the mug.
Here for 120, the expression for the start root and end root is given
<h3>What will be the expression for start root and enroot of 120?</h3>
Here we need to find 
By simplifying the given expression, we get:


by taking square roots on both sides we get
Thus for 120, the expression for the start root and end root is given
