5. Henry was building a rectangular fence around his garden. He has 84 feet of fencing. The width of the pen is
6 feet less than the length. Write an equation to find the
dimensions of the garden fence.

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
