PM+3x2, MN+xlk+4, and PN-18 = 32+3x+2, MN+9+4, and PN-18.

x = 9

PM = 32

Anybody disagree?

If these are line segments, then 3x + 2 + x + 4 = 18;

4x + 6 =18

4x = 12

x = 3 and PM = 11

the first one's right.. u just do pythagorean(not sure with spelling) theorem..
u have ur triangle then u just do 3x+2+x+4=18
4x=18-4-2
4x=12
x=3; then just substitute..PM=11
