F is between EG. If EF = 2x-12, FG = 3X-15 and EG = 23. find the values of x, EF, and FG.

The answer is A

Step-by-step explanation:

The first thing to do is see which two lengths of EF and FG equals EG which is 23. If you add together B's options you get -12 and if you add C's options, you get 77. So that leaves us with the options of A and D. From there, just plug in each value of x and see which one gets you the right values. Hope this helps
