What would the 863rd figure look like? 
This pattern repeats in 5's..
so there is a remaider of 3, so the third figure = 
863 div 5 = 172R3

What is the formula for the nth figure/number?
21, 30, 39, 48...
going up by 9 so, 9n+12
(1st number is 21, so 1x9=9, then adding 12 gets you to 21)
9n+12

What would the area of the 124th figure be? 
The area is: 3, 7, 11....
so formula = 4n -1, plug in 124:
(4times124 -1) = 496 -1=495

Factor Completely: (take out GCF, then Factor what is left over)
GCF = 3, so if you take out the 3 you have:
3(x^2+9+14)
then you can factor inside the parentheses: (order does not matter)
3(x+2)(x+7)
