Full solution

Q. Simplify the expression:

\newline

3(-7d) =

_____

Distribute $3$ to $-7d$ : First, we need to distribute the $3$ to the $–7d$ inside the parentheses. So we do $3 \times –7d$ .
Check for further simplification: Now we check if there's anything else to simplify, but there isn't. So, we're done!
