at its highest point the elevation of a county is 5,762 feet above sea level. At its lowest point the elevation of the county is 9 feet below sea level. Write an expression using integers to represent the difference between the elevations.

To represent the difference between the elevations of the county using integers:

- The highest point is **5,762 feet above sea level**, so this can be written as \( +5762 \).
- The lowest point is **9 feet below sea level**, so this can be written as \( -9 \).

The expression to represent the difference between the two elevations is:

\[
5762 - (-9)
\]

Simplifying the expression:

\[
5762 + 9 = 5771
\]

Thus, the difference between the elevations is **5,771 feet**.

Do you want more details or have any questions? Here are some related questions:

1. What is the absolute value of the lowest elevation?
2. How would the expression change if the lowest point was 15 feet above sea level?
3. What is the significance of the minus sign when dealing with below sea level elevations?
4. How can you visually represent this difference on a number line?
5. What if the highest elevation was twice as high? How would that affect the expression?

**Tip:** When subtracting a negative number, it is the same as adding its absolute value.

At its highest point the elevation of a county is 5,762 feet above sea level. At its lowest point the elevation of the county is 9 feet below sea level. Write an expression using integers to represent the difference between the elevations.
