Question

-(-5,2с-3,1d) - (2,4c+6,4d)-(5,2d+2,5c)​

Answer 1

Ответ:

(+5.2c-2.4c-2.5c) -(+3.1d-6.4d-5.2d) =0.3c-8.5d

Answer 2

To simplify this expression, we need to perform subtraction of vectors.

Let's first distribute the negative sign in front of the first set of parentheses:

-(-5,2c-3,1d) = (5,-2c+3,1d)

Now, we can subtract the vectors component-wise:

(5,-2c+3,1d) - (2,4c+6,4d) - (5,2d+2,5c)

= (5-2-5, -2c+3-4c-6, 1d-4d-2d-5c)

= (-2, -6c-3, -5d-5c)

Therefore, the simplified expression is (-2, -6c-3, -5d-5c).
