Which are the solutions of x2 = –7x – 8?

The solutions are:

Step-by-step explanation:

We have the following quadratic equation

We can rewrite the equation as follows

Now we use the quadratic formula to solve the equation

For an equation of the form the quadratic formula is:

In this case:

Then:

the answer is here: : )

:

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 %
