Tolong di bantu ya .. No 3 dan 4 aja pakai cara penerapan PLSV
bagas30
L = s x s 64 = 8 (x + 4) 64 = 8x + 32 64 - 32 = 8x 32 = 8x 32 : 8 = x 4 = x ------------------------------------------ rudi = x rini = x + 9 rini = 12 12 = x + 9 12 - 9 = x 3 = x 3 x 8 = x (8) 24 = x rudi = 24
64 = 8 (x + 4)
64 = 8x + 32
64 - 32 = 8x
32 = 8x
32 : 8 = x
4 = x
------------------------------------------
rudi = x
rini = x + 9
rini = 12
12 = x + 9
12 - 9 = x
3 = x
3 x 8 = x (8)
24 = x
rudi = 24
maaf kalo salah semoga membantu
