Question

Упрости выражения. b+5b+6b b=300 b+b+b b=300 c+c+2c c=50 d+d+d+d d=800 14p+20p+p p =80 4s+3s+7c s=20 9p+20p+8p p=80 10a+3a+2a a=30 t+2t+t+5t t=90

Answer 1

b+5b+6b=12b
12*300 =3600

b+b+b =3b
3*300 =900

c+c+2c =4c
4*50 =200

d+d+d+d =4d
4*800 =3200

14p+20p+p =35p
35*80=2800

4s+3s+7s=14 s
14*20=280

9p+20p+8p =37p
37*80 =2960

10a+3a+2a =15a
15*30 =450

t+2t+t+5t =9t
9*90=810

Answer 2

b+5b+6b, если b=300.
(300+1500+1800)b=3600b

b+b+b, если b=300.
(300+300+300)b=900b

c+c+2c, если c=50
(50+50+100)c=200c

d+d+d+d, если d=800
(800+800+800+800)d=3200d

14p+20p+p, если p=80
(1120+1600+80)p=2800p

4s+3s+7s, если s=20.
(80+60+140)s=280s

9p+20p+8p, если p=80
(720+1600+640)p=2960p

10a+3а+2а, если а=30
(300+90+60)а=450а

t+2t+t+5t, если t=90
(90+180+90+450)t=810t

Удачи ;)
