To calculate the square root, you can either use the √symbol on a calculator or you can manually find it using Prime Factorization. For non-perfect squares, Prime Factorization is the way to go.
The first two steps work for solving large perfect squares as well.
1. Divide your number into perfect square factors.
2. Take the square roots of your perfect square factors.
3. If your number doesn't factor perfectly, reduce your answer to simplest terms.
4. If needed, estimate. In some cases if you have memorized some of the square roots, you can estimate where the number would be.
ie.

you know that

and

, so you can estimate that the

would be between 7 and 8 but closer to 8.
5. <span>Alternatively, reduce your number to its lowest common factors as your first step.</span><span> Finding perfect square factors isn't necessary if you can easily determine a number's prime factors (factors that are also prime numbers).
ie. </span>

Hope this helped!!!
That would be 400 / 28 = 14.29 gallons to nearest hundredth
Answer:
Last Option moved
units right
Step-by-step explanation:
If we have a function f(x) and we want to move it horizontally then we make the transformation:

If
then the graph of f(x) moves horizontally h units to the right
If
then the graph of f(x) moves horizontally h units to the left.
In this case we have the function
and the transformation is performed to obtain 
Notice that in this transformation

<u><em>Then the graph of
moves horizontally
to the right</em></u>
Answer:
8x+2
Step-by-step explanation:
Or -8x+2 but i think its 8x+2
