to triple a number that was decreased by five you subtract 5 and then multiply by three. for example if you where given 10 you would 12-5=7 -> 7*3=21
A number decreased by 4 is n-4
"Decreased by" just means "minus," so that's C-11.
It is 5n - 8 <= 2n + 10

"Still" implies that the original number is a square number. In that case, the answer is as follows: There is no number such that it is a perfect sqiuare and that the number increased (or decreased) by 10 is also a perfect square. And if you do not limit it to perfect square then every non-negative number is a square with the number that is 10 more also being a square.
The expression is: 6x-10 which can be factored to 2(3x-5)
