Factor 8x−14. If the expression cannot be factored, write cannot be factored.

8x=2*4x
14=2*7
8x-14=2*4x-2*7
=2*( 4x - 7 )

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
