Question

Which expression is equivalent to (-18n) - 64n?

Answer 1

The given expression is (-18n) - 64n.

It can be simplified by taking outside the common factor -2. Hence,

`\begin{gathered} \mleft(-18n\mright)-64n=-2*9n-2*32n \\ =-2(9n+32n) \end{gathered}`

Therefore, the given expression is equivalent to -2(9n+32n).
