Looking at the numbers, we can see that the differences are 72, 36, and 18. Notice that they are each factors of the next by the same constant 2.
18 * 2 = 36
36 * 2 = 72
There, it means that 18/2 will be subtracted from 20.
20 - 18/2
= 20 - 9
= 11
The next number in the sequence would be 11. Hope this helps!
If your teacher was to randomly pick it would be 2:14
12x²y² + 2xy - 2
Work below:
(3xy - 1) (4xy + 2)
Apply FOIL.
= 3xy * 4xy + 3xy * 2 + ( -1 ) * 4xy + ( -1 ) * 2
= 3 * 4xxyy + 3 * 2xy - 1 * 4xy - 1 * 2
= 12x²y² + 2xy - 2
your answer.

Step-by-step explanation:
As the temperature decreases the number of people swimming will also decrease. This will create a negative correlation between the two factors.
