Mathematics

31 units

Step-by-step explanation:

Points E, F and G are collinear means they lie on the same line. Point F lies between E and G.

By Segment Addition Postulate,

EF+FG=EG

You are given EF = 2x +19, FG=6x-5 and EG=62.

By Substitution Property of Equality,

2x+19+6x-5=62

Solve this equation:

$2x+6x+14=62\\ \\8x+14=62\\ \\8x+14-14=62-14\\ \\8x=48\\ \\x=6$

Then

$EF=2\cdot 6+19=12+19=31\ units$

Points e, f and g are collinear. point flies between e and g. if ef = 2x +19, fg=6x-5 and eg=62, fin
