Question

3(5(-0,2)-4)-4(3(-0,2)+2)​

Answer 1

Ответ:

-9.4

Пошаговое объяснение:

3(5(-0,2)-4)-4(3(-0,2)+2)​=3*(-1-4)-4*(-0.6+2)=3*(-5)-4*1.4=-15-5.6=-9.4

Answer 2

To simplify the given expression, let's start by evaluating the expressions within parentheses.

First, let's evaluate the expression inside the parentheses on the left side: 5(-0.2) = -1

Now let's evaluate the expression inside the parentheses on the right side: 3(-0.2) = -0.6

Next, we substitute these values back into the original expression: 3(-1 - 4) - 4(-0.6 + 2)

Simplifying further: 3(-5) - 4(1.4)

Now we evaluate the multiplications: -15 - 5.6

Finally, we subtract the two values: -20.6

Therefore, the simplified result of the expression 3(5(-0.2) - 4) - 4(3(-0.2) + 2) is -20.6.
