Answer 2

To simplify the expression $(-x + 0.8y - 1.2c - 4) \times (-0.4)$, you can distribute the $(-0.4)$ to each term inside the parentheses and then combine like terms if possible.

$$\begin{align*} (-x + 0.8y - 1.2c - 4) \times (-0.4) & = -0.4 \times (-x) - 0.4 \times 0.8y - 0.4 \times (-1.2c) - 0.4 \times (-4) \\ & = 0.4x - 0.32y + 0.48c + 1.6 \end{align*}$$

Therefore, $(-x + 0.8y - 1.2c - 4) \times (-0.4) = 0.4x - 0.32y + 0.48c + 1.6$.
