Answer: 28.
Step-by-step explanation:
The median of a data set is defined as the middle value of a data set.
For instance, the median of the data set [4, 7, 8] would be 7 because it is the "middle value".
You can find this by sorting the numbers by smallest to largest:
2, 9, 15, 16, 21, 24, 28, 32, 34, 35, 37, 39, 40
There are 13 numbers in the set, so you can exclude the first 6 and last 6 numbers from the set to get your median, 28.
The degree is 2 becasuse of the x^2 and there are 3 terms so it is a trinomial.
