determine the factors of x2 − 12x − 20.

(x − 2)(x + 10)
(x − 10)(x + 2)
(x − 5)(x + 4)
prime

For this case we must indicate the factors of the following expression:

To factor we must find two numbers that when multiplied result in -20 and when added, result in -12.

There are no two numbers that meet this condition. Thus, the expression is not factorizable with rational numbers.

The expression is not factorizable with rational numbers.

10000000000000000000000000000000

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 %
