What solutions to the following quadratic
3x^2 +15x-18=0

x=-6 and x=1

Step-by-step explanation:

Given that:

Now,

Using the quadratic formula where a=3, b=15, and C=-18

x=-b±

x=-15±

x=-15±

the discriminant

So, there are two real roots

x=-15±21/6

Therefore, x=-6 and x=1

at home andrea has 1 2/3 kilograms of rice

step-by-step explanation:

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 %  

step-by-step explanation:
