Complete the table for the given rule. rule: y=3x Will give 5 star and

You did not prove the table, but my guess you either have a value for x or a value for y.

So, here's what you do.  If you have a value for x, then multiply that value by 3 and put it into the corresponding value for y.

If you have a value for y, then divide it by 3 and put it  into the corresponding value for x.

The perimeter is 80 meters
