Answer 1

Expression:
`(x+5,762)-(x-9)`

Simplified expression:
`5,762+9`

Explanation:

Let be "x" the sea level.

We know that the highest point of the country is 5,762 feet about the sea. Then, we can write the following expression:

`x+5,762`

Since the lowest point is 9 feet below sea level, we can write this expression:

`x-9`

The difference is the result of a subtraction. Therefore, we can find the expression that represent the difference between the elevations by subtracting
`x+5,762` and
`x-9`:

`(x+5,762)-(x-9)`

The expression simplified is:

`5,762+9`
