Answer:
the answer to the question is 39
Start at 4.
So far you have: 4
Now you go 7 units left. Going left means a subtraction. Going 7 units left means subtracting 7.

The result is -3.
The subtraction is:
4 - 7 = -3
Answer:

Step-by-step explanation:
This is the answer because it is subtracted so that you get the answer
As long as your indexes are the same (which they are; they are all square roots) and you radicands are the same (which they are; they are all 11), then you can add or subtract. The rules for adding and subtracting radicals are more picky than multiplying or dividing. Just like adding fractions or combining like terms. Since all the square roots are the same we only have to worry about the numbers outside. In fact, it may help to factor out the sqrt 11:

. The numbers subtract to give you -9. Therefore, the simplification is
