Need with this

what do median range mode and mean mean

Lets use this set of data as an example:
2,2,3,3,3,3,4,4,5

Median is the data number that is in the middle of all of the numbers when arranged from least to greatest.
The median would be 3 since its in the middle. THINK: Median=Medium

Range is the highest number minus the lowest number. This is easy.
5-2=3
So the range is 3.

The mode is the number that you see the most often. 3 is the most since there are four 3s. There can be more than one mode or even no mode. THINK: Mode=Most

The mean is all of the numbers added together and then divided by the number of numbers.
2+2+3+3+3+3+4+4+5= 29
29 divided by 9 = 3.2222222222(repeated)
The mean can also be called the average.

I hope this helps!!!

Since both terms are perfect squares, factor using the difference of squares formula:

a^2 - b^2 = (a + b)(a - b)

We know from the question that:

a = x + 1

b = 3

Now just plug it in:

(x - 2)(x + 4)

Thus, the answer is E.

Hope this helps! :)
