Answer 1

Ответ:

Пошаговое объяснение:

= -(16с+3с-5с)+(6,1d+2,9d+4d)=-13c+10d=23cd

Answer 2

To simplify the expression -(16c + 6.1d) + (3c - 2.9d) - (5c + 4d), you'll want to combine like terms:

First, distribute the negative sign to both terms inside the first set of parentheses:

-16c - 6.1d + (3c - 2.9d) - (5c + 4d)

Now, combine like terms by adding or subtracting coefficients of the same variables (c and d):

(-16c + 3c) + (-6.1d - 2.9d) - (5c + 4d)

Simplify each set of like terms separately:

(-13c) + (-9d) - (5c + 4d)

Now, combine the remaining terms:

-13c - 9d - 5c - 4d

Next, combine like terms again:

(-13c - 5c) + (-9d - 4d)

Simplify further:

-18c - 13d

So, the simplified expression -(16c + 6.1d) + (3c - 2.9d) - (5c + 4d) is equal to -18c - 13d.
