Yah, it helped me too.....    

log (3^x) = 9

x log 3 = 9

x = 9/log 3 =18.8663

Here is what might help:

The common ratio is the number to multiply a given term to find the NEXT term in the sequence...

5/6  x    = -4/9

x  =  -4/9 *  6/5 = -24/45 = -8/15 = common ratio

  I would make a small note   THIS is a  2012   w-2    make sure you use the tax rates for 2012.   ( I think they were the same in 2018...but maybe not !)

                  x^2+4x-34       -  22/(x-3)

x-3  |  x^3+x^2-46x+80

          x^3 -3x^2

        _______________

                  4x^2-46x

                  4x^2-12x

                _____________

                          -34x+80

                          -34x+102

                           __________

                (remainder)  -22

Basically with remainder  -22/(x-3)     then  p(3)  will equal -22

See cphill's explanation/answer here for the second part:

Malachai's  income is in the third row of the table......go across to Head of Household column to see Malachai owes  4199 in taxes....

your question did not state how much was withheld from his pay, so I cannot say if he owes.... or gets a refund.

(7x +5)(x-2)

P(x) / (x-7)  = x + 11/(x-7)      (given)  If you multiply both sides of this equation by (x-7) you will fid p(x)

p(x) =  x (x-7)   + 11

       = x^2 - 7x + 11      then put 7 in for 'x'  to find p(7) =  11

Cool!
