g is between f & h. FH= 8x, FG= 4x + 13, & GH= 22. What is the measure of FH?

hmm.. let's see: we are trying to figure out what x is and then plug it in the equation: length FG(4x+13)+lengthGH(22)=lengthFH(8x); 4x+13+22=8x; 4x+35=8x, subtract 4x on both sides: 35=4x, x=35/4. Can you solve it from here if you know what x is? FH=8x
