Answer 2

Ответ:

-(4,2c-2,1d)-(4d+2,3c)+(-2,2c+2,3d) =-4,2c+2,1d-4d-2,3c-2,2c+2,3d=(-4,2c-2,3c-2,2c)+(2,1d-4d+2,3d) = -8,7c+0,4d

Answer 3

To simplify the expression -(4,2c-2,1d)-(4d+2,3c)+(-2,2c+2,3d), we can expand and combine like terms:

First, distribute the negative sign to each term inside the parentheses:

-(4,2c-2,1d) becomes (-4,-2c+2,1d) -(4d+2,3c) becomes (-4d,-2,3c) -(-2,2c+2,3d) becomes (2,-2c-2,3d)

Now, let's combine the terms:

(-4,-2c+2,1d) - (4d,-2,3c) + (2,-2c-2,3d)

Combining the x-components:

-4 + 4d + 2 = 4d - 2

Combining the y-components:

-2c + 2 - (-2c) = 4

Combining the z-components:

1d - 3c + 3d = 4d - 3c

Putting it all together, the simplified expression is:

(4d - 2, 4, 4d - 3c)
