Yes, you can put parenthesis inside of parenthesis.
To make a box and whisker plot, you need to draw a number line that would be able to represent all the values in the data (look at your lowest and highest numbers).
You will need to graph the following 5 points on your number line (median, lower quartile, lower extreme, upper quartile, and upper extreme).
Create a box around the quartiles and extend the lines to the extremes.
See the picture I have attached for the box and whisker box for this data set.

Step-by-step explanation:
Distance Formula: 
Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:





Answer:
AC=9 cm
ABC is not a right angled triangle
Step-by-step explanation:
AB=8cm
BC=5cm
22=AB+BC+AC
AC=22-8-5
AC=9
since AC is the longest,
using Pythagoras theorem
AC^2=BC^2+AB^2
9^2=8^2+5^2
81=64+25
81=89
therefore, it is not a right angled triangle
