Rewrite the Equation in Standard Form $$x ^ { 2 } + y ^ { 2 } - 16 x + 39 = 0$$

Multiple Choice

Rewrite the equation in standard form. Find the center and radius of the circle.
- $$x ^ { 2 } + y ^ { 2 } - 16 x + 39 = 0$$

A) $( x - 8 ) ^ { 2 } + y ^ { 2 } = 25$
center $( - 8,0 ) , r = 5$
B) $x ^ { 2 } + ( y - 8 ) ^ { 2 } = 25$
center $( 0,8 ) , r = 5$
C) $( x - 8 ) ^ { 2 } + y ^ { 2 } = 25$
center $( 8,0 ) , \mathrm { r } = 5$
D) $( x + 8 ) ^ { 2 } + y ^ { 2 } = 25$
center $( - 8,0 ) , r = 5$
