Answer:
the answer is 144 feet
Step-by-step explanation:
to find the how long each sides of the square is divide 48 by 4 (because that's how many sides there are on a square). by doing that you get 12
to find the area of the square you do A= lw which in this case it would look something like this:
A= 12(12) you use 12 twice because square sides are always equal
then you multiply which gives you A= 144
The answer for this problem is 7
Answer:
a difference of squares
Step-by-step explanation:
Let's write down the expression:

we can see that this expression is one of the form
which is the general expression of a difference of squares.
To be more specific and to see why we say this, let's make
and 
Now, if we substitute this in the general formula, we get:

Thus, this expression is a difference of squares.
