Answer:
3^2, 9 students.
Step-by-step explanation:
I'm not 100 percent sure about this but I'm pretty sure that because there are 3 rows you can just do 3^2 which is 9.
Ex: l -3 l = 3.
the two vertical lines on either side stand for absolute value, or the distance to 0 from the given number.
THE ANSWER WILL ALWAYS BE POSITIVE (except...)
however, if there is a negative sign on the OUTSIDE of the bars, the answer will be NEGATIVE.
ex: - l -4 l = -4
ex: l -4 l = 4
