When written in standard form, the product of (3 + x) and (2x - 5) is
3x - 2
2x² + x - 15
2x² - 11x - 15
6x - 15 + 2x² - 5x

2x² + x - 15

Step-by-step explanation:

standard form is denoted as:

ax² + bx + c

(3+x)(2x-5)

6x + 2x² - 15 -5x

2x² + x - 15

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 %
