Wha is the equation of a circle with center (-3, -5) and radius 4

(x  + 3)² + (y – 5)² = 16

Step-by-step explanation:

Equation of a circle is (x – h)² + (y – k)² = r²

h is the x of the point, so -h = 3

k is the y of the point, so -k = 5

r is the radius so r² = 4² = 16

so

(x  + 3)² + (y – 5)² = 16

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
