The distance between A (-4, 2) and B(4, 2) is.

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142

Change negative exponents to positive, then solve

27/9=18/x a. x=9 b. x=18 c. x=6 d.x=3
