How do I write five times the quantity of a number and 3 is 50

Step-by-step explanation:

let the number be x :

The center of circle is (2, -5) and radius is 6.

Step-by-step explanation:

Given : The equation of circle

We have to find the center and radius of a circle with the given equation

The standard equation of a circle with center (h,k) and radius r is given by

Grouping  x and y terms together, we get,

Convert x to square by adding 4 both side, we get,

Simplify, we get,

Convert y to square by adding 25 both side, we get,

Simplify, we get,

Rewrite in standard form, we get,

Therefore, (h, k) = ( 2,-5) and radius = 6

Thus, the center of circle is (2, -5) and radius is 6.
