A number tripled is a number multiplied by 3. For the variable x, x tripled would be 3x.
Ummm... I really don't know what you are trying to ask with this question so I will answer your question with variables. An unknown number tripled is 3x So you can substitute any number for x and it will be tripled. For example: if x=2, then the answer would be 6, which is tripled from 2.
If you can compile a complete list of all different rectangular models with sides of integer length for a number then their lengths and breadths represent its factors.
301 is a rectangular number
3n + 100
72 is rectangular.
That would be -4 .
Because a cube IS a rectangular prism ... one where the length, the width, and the height just happen to be all the same size.
