Daca x=10 si a+b=8 Aflati:
a) 3x+3a+3b; b)x+5a+5b; c) ax+bx    Va rog ajutati-ma! :*


Răspuns :

x=10 a+b=8 a)3*10+3*8=30+24=54 b)10+5*8=10+40=50 c)a*x+b*x= 8*10la 2=8*100=800
a)3x+3a+3b=3x+3(a+b)=3x10+3x8=30+24=54
b)x+5a+5b=x+5(a+b)=10+5x8=10+40=50
c)ax+bx=(a+b)x=8x10=80
e cel mai bun raspuns?marcheaza-l.multumesc!
