kobusy [5.1K]

Answer:

4(2x-3)(2x+3)

Step-by-step explanation:

The first thing you would do is find the greatest common factor (the biggest number that goes into both of them.

Common factors

1,2,4

So the greatest common factor would be 4 so then you would divide both numbers by 4 and bring it to the outside like so.

4(4x2 - 9)

then you would take it out to where it would multiple to get the same number, like this.

4(2x-3)(2x+3)

Can you find sets of positive integers that satisfy the following?
Hitman42 [59]

Answer:

{ 6 ,6 , 6, 7 , 10 } , { 5 , 6 , 6 , 8 , 10 }  ,  { 4 , 6 , 6 , 9 , 10 } , etc. (There's a lot more)

Explanation:

Mean of a set is equal to the terms added divided by the number of terms.

Median is the middle number when you order out the terms in the set in the increasing order from left to out.

Mode is the most occurring term.

Now, since the mean of five number  

{ v , w , x , y , z }  is  7 , we have:  v + w + x + y + z 5 = 7  => v + w + x + y + z = 35

Now, the middle term, the median, is 6.

Now we have:  

{ v , w , 6 , y, z }

Since the mode is 6, there has to be at least two 6.

There isn't enough limitations to have one answer.

For example, you could have this:

{ 4 , 5 , 6 , 6 , 14 }

The values add up to 35, the middle term is 6, and 6 is the most occurring.

You will find many other sets possible.

Step-by-step explanation:

Use this way to solve the rest.
