Answer:
5
Step-by-step explanation:
To find the median number of
3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7
Number them from least to greatest
2 2 2 2 3 3 3 4 5 5 6 7 7 7 7 7 9 53
Since this isn't an even numbered set, all we do is cancel each number out equally on both sides until only one number which should be in the middle is left. This gives you an answer of 5
Hope this helps!

Step-by-step explanation:
If you want to make

into a perfect square binomial, take half the linear term, square it, then add it to both sides. Our linear term is 12. Half of 12 is 6, and 6 squared is 36.
The value that makes this a perfect square binomial is 36.
Writing the expression as a square of the binomial is:
