0 is considered a solution because when you multiply both 4 and 2 by 0, you always get 0. when you add 10 to 0 you get zero, meaning that you get the same answer for both sides.

What is the equations of a circle at (4,5) and a radius of 2

Savatey [412]

Equation of any circle with (a,b) as its center, and on (x,y) coordinate, with radius r, is:
$(x-a)^2+(y-b)^2=r^2$
so here the center is at (4,5) with radius of 2, so,
The equation of this circle is:
$(x-4)^2+(y-5)^2=4$

Hope this helps.

For a contest, Dominique is stacking 3 super-long pens lengthwise on top of each other. Each pen is 2 feet long. If she succeeds
