Answer:
9.42
Step-by-step explanation:
Begin by factoring 2 out of 2x^2 - 2x - 12 equals 0:
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0. 2 is never zero, but x-3 and x+2 can each be set = to 0:
This results in x = 3 and x = -2. The equation is true for these two x-values.

Answer:
see below
Step-by-step explanation:
Pedro has 3 boxes of 6 markers.
3*6 = 18 markers
We can divide this by 2 because this is even
18/2 = 9
There are 9 in each group
Rafael has 5 boxes of 5 markers
5*5 = 25
We cannot divide this by 2 because this is odd
