5√2-3√2.

​

=====================================

Explanation:

Let's say we replace every copy of with x

Doing so means we have the expression 5x-3x. That simplifies to 2x.

The last thing to do is replace the x with and that's how we end up with as the final answer.

----------

In short: we subtract the numbers out front, and then tack on a root 2 at the end.

As another example,

This is basically the same as saying 19x-11x = (19-11)x = 8x where

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

answer is c
