unit 5 relationships in triangles home work 2 perpendicular and angle bisectors: determine if S could lie on the perpendicular bisector of line QR with the given coordinates: Q (-5, -1), R (3,7), S (4, -2)

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

the answer is a if my teacher taught me correct
