Answer:
RS = 5
Step-by-step explanation:
Since R is between Q and S , then
QS = QR + RS , that is
6x - 3 = 3x - 2 + 2x + 1
6x - 3 = 5x - 1 ( subtract 5x from both sides )
x - 3 = - 1 ( add 3 to both sides )
x = 2
Then
RS = 2x + 1 = 2(2) + 1 = 4 + 1 = 5

Answer: Isn't a circle always 360??
Step-by-step explanation:
Solve for x
4 12
--- = --- 4x=36 36/4=9 x=9 = PQ=9in
3 x
4 18
--- = --- 4x=54 54/4=13.5 x=13.5 QR=13.5in
3 x
4 24
--- = --- 4x=72 72/4=18 x=18 PR=18in
3 x
18+13.5+9 = 40.5
Therefore, the perimeter of ΔPQR = 40.5inches
