show your work.

  14 +11i

Step-by-step explanation:

The product of binomials is found in the usual way, except that i² = -1.

  (1 -3i)(2 +5i) -(3 -12i)

  = (1·2 +1·5i -3i·2 -3i·5i) -3 +12i

  = (2 +15 -3) +i(5 -6 +12)

  = 14 +11i

the answer will be the last one

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
