Which of the following expressions are equivalent to -9.7 • -0.8 • -7.8 • 3.8

41/17 as a decimal rounded to the nearest hundredth

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

Can someone show me step by step how to do this?
