which equation would best solve the problem?

a) 48 = x (x - 4)
b) 48 = x^2 - 4
c) 48 = 1/2(x)(x - 4)
d) 48 = 1/2(x^2 - 4)

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36
