Final answer:
To simplify the expression |x+3|, when x>5, the simplified expression is x+3.
Step-by-step explanation:
To simplify the expression |x+3|, we need to consider the value of x based on the given condition x>5. When x>5, x+3 is always positive, so |x+3| simplifies to x+3.
For example, if x=6, |6+3|=9. If x=7, |7+3|=10. And so on.
Therefore, when x>5, the simplified expression of |x+3| is x+3.
