tolong kerjakan no 9 - 13 dgn caranya yg benar yah

itu untuk no 9 ya
maaf kalo salah

9.
3x - 4 = x + 10
2x = 14
x = 7

AD = 3x - 4 = 3.7 - 4 = 17 cm

10.
5x = 180
x = 36

2x36 = 72
3×36 = 108

11.
x + 5 + 3x - 25 = 180
4x - 20 = 180
4x = 160
x = 40

sudut L = sudut N
3x - 25 = 3 × 40 + 25 = 95

12.
Luas = 8 × 7 = 56

13.

Luas = 9×12 = 108
