a glacier receded 4 feet a day for a period of 25 days. how much shorter was the glacier at the end of the period.
dangina [55]

Alright, lets get started.

In the question given that glacier receded 4 feet a day for a period of 25 days.

Which shows in 1 day, it recedes = 4 feet

means in 1 day, the height of the glacier gets shorter = 4 feet

So, in 25 days, the height of the glacier gets shorter = 4 * 25

So, in 25 days, the height of the glacier gets shorter = 100 feet

It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer

Hope it will help :)

Under what conditions are we allowed to add or subtract radicals together?
Liula [17]

Answer/Step-by-step explanation:

The conditions where we are allowed to subtract or add radicals together is when the radicands, which is the number inside the radical, of both radicals are the same. And also, when they both have the same indices, that is, for example, they have the same root.

Take for example the following radical expression:

4\sqrt{2} + 3\sqrt{2}

Both radicals, 4\sqrt{2} and 3\sqrt{2}, have the same radicand, \sqrt{2} , and also the same index of square root.

Therefore, they are regarded as like terms, and can be added or subtracted together.

Thus,

4\sqrt{2} + 3\sqrt{2} = 7\sqrt{2}
