Hello there, and thank you for posting your question here on brainly.
Short answer: C. 9
Why?
Box and whisker plots are confusing, the line in the middle is the median, but we don't need to do that now. The dots on the lines outside of the box show the largest and the shortest number. The plotted point on the way left is your answer, the line plotted is 9.

Answer:
5
Step-by-step explanation:
If an expression is the difference of two squares, it will follow this format:

where a and b are integers or variables.
1)

Since the expression follows the format, it's a DoTS.
2) Since the binomial has an addition sign, it isn't a DoTS.
3)

The second term isn't an integer, so the expression isn't a DoTS.
4)

Since the expression follows the format, it's a DoTS.
Therefore, the first and fourth expressions are differences of two squares.
