ajutatima va rog frumos ​

Answer 1

Răspuns:

6)

2(a+b+c)=2·7=14

10(a+b+c)=10·7=70

13(a+b+c)+21=13·7+21=91+21=111

8(a+b+c)-12=8·7-12=56-12=44

400-5(a+b+c)=400-35=365

6(a+b+c)+100=42+100=142

7)

a(b+c)=11·8=88

2·11+3·8=22+24=46

10·11+9·8=110+72=182

a(b+c)+25=11·8+25=88+25=113

a(b+c)-34=11·8-34=88-34=54

7·8+9·11=56+99=155

11·8-6·11=88+66=154

3·11-(3·8)=33-24=9

11(b+c)=11·8=88

9)

13(21+5+40)=858

437(109-54+203)=258·437=112746

49(135-27+11)=49·119=5831

2(1+2+3+4+5+6)=2·21=42

13(17+25)-2(21·11+41)=546-544=2

10)

a(b+c)=6·157=942

a(b-c)=25·147=3675

a(b+c+d)=14·59=826
