if there is some one out there that can help me finish some math can you be so kind to help me plz thanx :) ps: last question at least 50 points

If the scale factor between two circles is 2x/5y what is the ratio of their areas?

Segment wx is shown explain how you would construct a perpendicular bisector of wx using a compass and a straightedge

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
