Question

E At its highest

Answer 1

Answer:

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

Simplified expression: $5,762+9$

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:

$x+5,762$

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:

$5,762+9$
