Question

розкрий дужки:
1) 3(c+d)=
2) 6(4+b)=
3) a(3+7b)=
4) -2(6a+12)=
5) 10(3m-4)=
6) b(5-7a)=​

Answer 1

Ответ:

1) =3c+3d

2) = 20+ 6b

3) =3a+7ab

4) =-12a-24

5) =30m-40

6) =5b-7ab

Answer 2

1) 3(c+d) = 3c + 3d

2) 6(4+b) = 20 + 6b

3) a(3+7b) = 3a + 7ab

4) -2(6a+12) = -12a - 24

5) 10(3m-4) = 30m - 40

6) b(5-7a) = 5b - 7ab
