What is the value of 9(n+2)−5n for n=14?

Answer 1

Replace every n with 14


\[\Large 9(n+2)-5n\]

\[\Large 9*(\color{red}{n}+2)-5*\color{red}{n}\]

\[\Large 9*(\color{red}{14}+2)-5*\color{red}{14}\]

Answer 2

Now use PEMDAS to evaluate `9*(14+2)-5*14` and tell me what you get

Answer 3

Answer 4

Please, IPS: share all of your work if you want feedback on it.

Answer 5

Same idea. Replace every n with 1/4


\[\Large 9(n+2)-5n\]

\[\Large 9*(\color{red}{n}+2)-5*\color{red}{n}\]

\[\Large 9*(\color{red}{1/4}+2)-5*\color{red}{1/4}\]

then use PEMDAS
