Question 1169024
<font face="Times New Roman" size="+2">


With the information given, the value of *[tex \Large x] could be anything you like.  You did not specify what *[tex \Large x] represents, so there are no restrictions whatsoever on its value.  That being said, if *[tex \Large x] represents a length, then you can certainly throw out the two negative answers since a negative length is absurd.
