What is a faster way to do long division? examples would be greatly appreciated

Let w=23 . what is the value of w + 45 ?

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

Solve this problem! extra ! 3025/5.5 = a/90.75
