Answer 1

Ответ:

1) 15 * (a + 12) = 15a + 180

2) c * (8 - 11d) = 8c - 11cd

3) 6 * (2n + m) = 12n + 6m

4) (n-m) * 15p = 15np - 15mp

5) 3 * (2p + k + 5t) = 6p + 3k + 15t

6) 5 * (a + 5) + 4(a + 6) = 5a + 25 + 4a + 24 =9а + 49

7)(y+8) * 10+(5-y) * 6 = 10y + 80 + 30 - 6y = 4y + 110

8) (4m+9)*5+3* (5m 6) + 8* (4m - 5) = 20m + 45 + 15m - 18 + 32m - 40 = 67m - 13

Пошаговое объяснение:

45) 1) 9 • (a + b)

2)5•(c+2d)

3)4• (2n-3m)

4)2•(n + 8m)

5)5•(3p+k- 5t)

6)2•(6p-7k + 3t)
