If a(x) = 2x - 4 and b(x) = x + 2, which of the following expressions produces a quadratic function?

consider D for a second. (a + b) × would give you (2×-4) + (× + 2) = 3×-2 which is not a quadratic

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 %
