Line 4
It should be font-size: 15px
Also there should be curly braces in line 5.
The connector for ethernet cables is called RJ45. for phone jack is RJ11. Although they look the same, the RJ11 has only 4 leads, as opposed to 9 leads in RJ45. Also, RJ11 is not as wide as RJ45, so the connector does not fit.
Even if it would, the signals would be totally incompatible, so no success can be expected.
16235 to the nearest ten thousand would be 20,000.
Hope this helps :)
