Answer 2

To simplify the expression $(7a+b+c) \cdot (-3ab \cdot c)$, you can apply the distributive property (also known as the distributive law or FOIL) to multiply the terms in the first set of parentheses by the terms in the second set of parentheses:

$$\begin{align*} (7a+b+c) \cdot (-3ab \cdot c) &= 7a \cdot (-3ab \cdot c) + b \cdot (-3ab \cdot c) + c \cdot (-3ab \cdot c) \\ &= -21a^2bc - 3abc^2 - 3abc^2 \\ &= -21a^2bc - 6abc^2. \end{align*}$$

So, the simplified expression is $-21a^2bc - 6abc^2$.
