YANG JAGO MTK TOLONG BANTUIN DONG MAU DI KUMPULIN NIH​

Penjelasan dengan langkah-langkah:

(1)

x/10 = 2/(2+3)

x/10 = 2/5

x = 2(10/5)

x = 2(2)

x = 4 cm

(2)

4/x = 6/(3+6)

4/x = 6/9

6x = 4(9)

6x = 36

x = 36/6

x = 6 cm

(3)

8/(8+x) = 6/9

6(8 + x) = 8(9)

8 + x = 72/6

8 + x = 12

x = 12 – 8

x = 4 cm

(4)

(20 x 18 + 50 x 12) 360 + 600

PQ = ------------------------- = ------------------

18 + 12 30

960

PQ = -------- = 32 cm

30
