/2
Step-by-step explanation:
12 is the answer your looking for
Answer:
D) x = -12 or x = 2
Step-by-step explanation:
The given quadratic equation is:

When y=0, we obtain:

We split the middle term with -2, 12 because their product is is -24 and their sum is 10.

We factor by grouping to obtain:

Answer:
1/4 or 25%
Step-by-step explanation:
The probability for rolling an odd number is 50% or
because there are 3 odd numbers, (1, 3, 5) and 6 total outcomes (1, 2, 3, 4, 5, 6). 
The probability for rolling two odd numbers in a row is

So, the probability of rolling an odd number twice is 25% or
