If EF bisects CD, CG= 5x-1, GD= 7x-13, EF= 6x-4, and GF= 13, find EG

Set $r$ is a set of rectangles such that (1) only the grid points shown here are used as vertices, (2) all sides are vertical or horizontal and (3) no two rectangles in the set are congruent. if $r$ contains the maximum possible number of rectangles given these conditions, what fraction of the rectangles in set $r$ are squares? express your answer as a common fraction.

Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -5x + 4

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping
