Answer:
Both of these examples are wrong. You cannot add/subtract integers and square roots together, however, you could add square roots together if they have the same number under the square root. For example, 2 - 2√6 will stay as 2 - 2√6 because they aren't like terms. 25 + 5√5 + 5√5 + 5 = 30 + 10√5 because 25 + 5 = 30 and 5√5 + 5√5 = 10√5. We can add 5√5 and 5√5 together because they have the same number under the square root. If we were to compute √2 + √3, we would just leave it as is because they don't have the same number under the square root.

Answer: 760 feet
Step-by-step explanation:
So, 220 feet is 1/3 of the mountain.
Now, multiply 220 x 3 = 660.
The top of the mountain is 660 feet.
The bottom of the lake is -100 feet.
Now just simply add 100 + 660 = 760
So, the total elevation change is 760 feet.
