Answer:

Step-by-step explanation:
Given:

We need to complete this Statement.
By Solving the above equation we get;
We will take some common factor out so we will get;

Hence the Complete statement is 
I would say (I am abbreviating square root to sqrt)
1. 4 sqrt(8488) = 4 sqrt(2x2x2122) = 8 sqrt(2122)
2. 3 sqrt(6936) = 3 sqrt(6x34x34) = 102 sqrt (6)
3. 2 sqrt(8648) = 2 sqrt(2x2x2162) = 4 sqrt(2162)
A. Multiplication is the ONLY function that reverses what division did. If you did 56/-14 = n, then n x -14 should equal 56.
Yes it determine the length
17/30 or .56 is your correct answer
