Answer 2

Ответ:

Пошаговое объяснение:

1.

1) = 4а + 4b

2) = 6x - 6y

3) = -4n - 4m

4) = -9n + 9m

5) = 14x - 42y

6) = -8a - 16c

7) = -6b + 18n

8) = -4,5n + 6a

9) = -1,2a + 0,6b

10) = 0,5 + 1a - 30c =

0,5 + a - 30c

11) = -0,14a + 1,2b - 0,9c

2.

1) = x + b + d - c

2) = y - d - b + c

3) = z + b - c + n

3.

1) = 11x

2) = 6x

3) = 8x + 2y

4) = 5x - 6y

5) = 22x + 9y

6) = 23x - 30y

4.

1) = 4x - 4y + 4x = 8x - 4y

2) = -8x - 64y - 6x =

-14x - 64y

3) = -40 + 10c - 5c =

-40 + 5c

4) = -4x + 8y - 14x - 21y = -18x - 13y

5) = 4x - 8y - 42x - 18y = -38x - 26y

6) = -6x + 2y + 48y - 12x = -18x + 50y
