Answer:
( x + 9)² + y² = 20
Step-by-step explanation:
The standard equation of a circle is ( x – h)² + ( y - k)² = r², where the center is (h, k) and r is the radius. By plugging in the given numbers from the question, we have [ x – (-9)]² + ( y - 0)² = (2√5)².
( x + 9)² + y² = (2)(√5)(2)(√5)
(2)(2) = 4 (√5)(√5) = 5 (4)(5) = 20
( x + 9)² + y² = 20
