A rectangle is three times as long as it is wide. Determine a simplified expression that shows how the area will change if the length is decreased by 2 and the width is increased by 3.

Please show your work

Thanks :)

Hello Julius,

I would like to help you work this out rather than just doing it for you.

What is the area of any rectangel?

A rectangle is three times as long as it is wide.

**Let the width be w.**

What is the length?

What is the area?

length is decreased by 2 and the width is increased by 3

What is the new width and length in terms of w?

What is the new area?

Now compare the old area to the new area. :)
