Aswimming pool 25m by 10m has a concrete border. find the area of the concrete border if it is 2.5m wide at the sides and 5m at the ends.

In the coordinate plan (-6,9) b (3,9) c (3,3) def is shown in the coordinate plan below

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)

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
