Given b is the midpoint of AC. AB=6x+7 and BC is 18x-4 what is the length of AB BC AC

• Geometry -

Sinve b is midpoint of ac then ab and ac are the same length. So, 6x+7 = 18x-4.
Hope this helps.

• Geometry -

Then what do I do with 6x+7 = 18x-4

• Geometry -

Uh, solve to see what x is. Then use that value to evaluate AB and BC. They should come out the same.

If you're taking geometry, a little algebra I should be no problem...
