Heguy heres my question if abcd is a parallelogram, which of the following statements must be true

Have you given this problem any thought?  It'd be great if you were to share your thinking.  The 2nd answer is correct.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
