Is it x times 2 times y times 2? is that what it is asking or is it meaning squared
<h3>
Answer: 5</h3>
=================================================
Explanation:
Let's consider the expression (x-y)^2. It expands out to x^2-2xy+y^2. The terms are:
Each of those terms either has a single variable with an exponent of 2, or has the exponents add to 2. Think of 2xy as 2x^1y^1.
In short, this means that the degree of each monomial term is 2.
----------
Now consider (x-y)^3. It expands out into x^3-3x^2y+3xy^2+y^3.
We have terms that either have a single variable and the exponent is 3, or the exponents add to 3. The degree of each term is 3.
----------
This pattern continues.
In general, for (x-y)^n, where n is any positive whole number, the degree of each term in the expansion is n. If you picked any term, added the exponents, then the exponents will add to n.
using the given coordinates, the rectangle is 7 by 3 units
area = 7*3 = 21 square units
bro.. i don't think someone is gonna answer all this for you, you should like figure this out on ur own..
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or 
or 
When a base with an exponent is divided by a base with an exponent, you subtract the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(can't combine because they have different bases of y and x)
When you multiply an exponent directly to a base with an exponent, you multiply the exponents together.
For example:
First multiply the exponents together in the denominator
Now subtract the exponents together
(two negative signs cancel each other out and become positive)
