Answer:
Considering the given equation 
And the ordered pairs in the format 
I don't know if it is log of base 3 or 10, but I will assume it is 3.
For 


So the ordered pair will be 
For 


So the ordered pair will be

So the ordered pair will be 
5. The 5th figure will have 30 tiles.
6. The 6th figure will have 42 tiles.
7. The pattern is non-linear (quadratic).
8. The 20th figure can be made with 420 tiles.
_____
The Nth figure is made with n*(n+1) tiles. To answer question 8, you must solve
.. n(n +1) = 420
.. n^2 +n -420 = 0
.. (n +21)(n -20) = 0
.. n = 20 or -21 . . . . the negative solution is extraneous
Ok use a calculator and do 11 x 11 x 4 then 7 x 7 x 4 and add the products
Two hundred thirty-five and six hundred seventy-eight thousandths
10c^4 * 4 c^2
40 c^2
we need to know the value of c to evaluate
