Question

Раскрой скобки: 3 (a+8); 8 (6-y); (x-9)*11; 12 (5a-6); 7 (5x+7y-6t); (2a+5b-3c)*14; 

Answer 1

3 (a+8)=3а+24;
8 (6-y)=48-8у;
(x-9)*11=11х-99;
12 (5a-6)=60а-72;
7 (5x+7y-6t)=35х+49у-42t;
(2a+5b-3c)*14=28a+70b-42c

Answer 2

1)3(а+8)=3а+24
2)8(6-у)=48-8у
3)(х-9)×11=11х-99
4)12(5а-6)=60а-72
5)7(5х+7у-6t)=35x+49y-42t
6)(2a+5b-3c)×14=28a+90b-42c
