ditanya:
L=
jawaban:
K = 2p+2l
= 60cm
60cm= (n+6)x2
n = 48:2
= 24
b. 6p-4p=6+12, 2p=18, p=9
c. x+3=5×2, x=10+3=13
2. a. 75= (x+30)+(2x+5)+ (3x-20)
75=6x+15
b. 75=6x+15 90=6x, x=15 x+30=45
2x+5=35 3x-20=25
3. 2(p+l)=60 p=6+l L=p×l
(6+l)+l=30 = (6+12)×12
2l=24 =18×12=216 cm
l=12
5. 12×(x+3) ≤84
x+3≤7
x≤ 4
