Mean:
Add all the numbers:
13 + 17 + 15 + 18 + 21 + 13 + 20 + = 16.7
16.7 + 3.7 = 20.4
Mean = 20.4
Median:
Order the numbers:
13, 13, 15, 17, 18, 20, 21
The median, or middle number is 17.
17 + 3.7 = 20.7
Median = 20.7
Mode:
The number that repeats the most is 13.
13 + 3.7 = 16.7
Mode = 16.7
Range:
Highest Number = 21
Lowest Number = 13
21 - 13 = 8

Factor the equation. Remember the value should add to the b value and multiply to the c value.
x^2-x-12= 0
(x-4)(x+3)=0
Use the zero product property to find roots
x-4=0
x=4
x+3=0
x=-3
Final answer: x=-3, x=4
