Full solution

Q. Simplify the expression:

\newline

-7(-4r) =

_____

Multiply by $-4r$ : First, we need to multiply $–7$ by $–4r$ . Remember that a negative times a negative is a positive. So, $–7 \times –4r = 28r$ .
Check for correctness: Now, we just check if we did everything right. Multiplying two negatives gives a positive, and $7$ times $4$ is $28$ , so it looks good.
