Question

Write an equivalent expression by distributing the "-" sign outside the parentheses:-(-9.1d - 6f +9.1)

Answer 1

Given an expression

`-(-9.1d-6f+9.1)`

To distribute the above expression, multiply through by minus sign

`\begin{gathered} -(-9.1d)-(-6f)-(+9.1) \\ 9.1d+6f-9.1 \end{gathered}`

Hence, the equivalent expression by distributing the "-" sign outside the parentheses is

9.1d + 6f -9.1
