combine like terms:
3x + 5x

(x – h)² + (y – v)² = r².

Step-by-step explanation:

Given  : A circle with a radius of r and center at (h,v).

To find : which of the following is the equation for a circle .

Solution : We have given radius = r center = ( h ,v) .

Standard form of circle : (x – h)² + (y – k)² = r².

Where, center ( h ,k ) ,radius = r.

On plugging the values in standard equation

(x – h)² + (y – v)² = r².

Therefore, equation of circle (x – h)² + (y – v)² = r².
