To solve this problem you must apply the proccedure shown below:
1- You have the following quadratic expression <span>n^2-25.
2. When you factor, you obtain:
(n-5)(n+5)
3. To verify this is true, you can apply the distributive property, as below:
</span><span>n^2+5n-5n-25
</span><span>n^2+25
Therefore, as you can see, the answer is the second option, which is:
(n-5)(n+5)</span>

Step-by-step explanation:
The degree of a polynomial is usually the highest degree in the function.
Answer:
Quadrant 1!!!
Step-by-step explanation:
Hello, this is a linear problem so we are working with y = mx + b
The problem tells us:
y = total cost
x = the megabytes of data that she used in a month
b = y-intercept, which is the initial value
The problem asks "Which part of the graph will represent the cost per megabyte of data used in each plan?"
It is asking for cost per megabyte... This is a rate. and m = slope = rate
So lets, reiterate.
y = total cost
x = the megabytes of data that she used in a month
b = y-intercept, which is the initial value
m = slope = rate = cost per megabyte of data used
Answer: The slopes of the two lines.
