Answer:

Expression: [tex](x+5,762)-(x-9)[/tex]

Simplified expression: [tex]5,762+9[/tex]

Step-by-step 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:

[tex]x+5,762[/tex]

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

[tex]x-9[/tex]

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

[tex](x+5,762)-(x-9)[/tex]

The expression simplified is:

[tex]5,762+9[/tex]
