Answer 1

GIven:

`-(-8.4n-1)`

To Determine: The equivalent of the given expression

Distributing the sign outside as shown below:

`\begin{gathered} -(-8.4n-1) \\ =-*-8.4n-*-1 \\ =8.4n+1 \end{gathered}`

Hence, the equivalent expression by distributing the sign outside the given expression is:

8.4n+1
