A square has a perimeter of 40 m. What is the length of each side?

1 ≥ x - 9 Find out what x means.

BigorU [14]

So first +9 to both sides to isolate the variable. Then you’ll be left with 10 is greater than or equal to x. So if you switch the terms around it’ll be x is less than or equal to 10. Values that are less than or equal to 10 are like 10,9,8,7,etc.
