2
+ 24x + 28y + 24 = 104. Which option is the correct standard form with center and radius?
A
(x - 6)
2
+ (y - 7)
2
= 125; center (6, 7); radius sqrt(125)
B
(x - 6)
2
+ (y + 7)
2
= 125; center (6, -7); radius sqrt(125)
C
(x + 6)
2
+ (y - 7)
2
= 125; center (-6, 7); radius sqrt(125)
D
(x + 6)
2
+ (y + 7)
2
