Пошаговое объяснение:

Для начала раскроем скобки:

-0,4*(3в+4) = -1,2в - 1,6

Подставляем в:

= -8,4 - 1,6 = -10

Answer 2

-0,4*(3+4)=-1,2 - 1,6=-8,4 -1,6--10

Answer 3

To evaluate the expression -0.4*(3v + 4) when v = 7, we substitute the value of v into the expression and perform the calculations.

Let's plug in v = 7:

-0.4*(3 * 7 + 4)

First, we calculate the value inside the parentheses:

3 * 7 + 4 = 21 + 4 = 25

Now we substitute the value back into the expression:

-0.4 * 25

Finally, we perform the multiplication:

-0.4 * 25 = -10

Therefore, when v = 7, the value of the expression -0.4*(3v + 4) is -10.
