Just for future reference always put ^ for exponents. The answer is y-6 though.
(y-4)(y-6) create that trinomial. You can prove that by using the FOIL algorithm
Answer:
A: -6
Step-by-step explanation:
Flip around the question
what is 12 - 18
If you count the numbers in between 12 and 18
You get 6
So now just make the answer negative
Answer:

Step-by-step explanation:
We need to find the solution to the following system of equations:
and 
By plugging the value of 'y' into the first equation we have that:
⇒ 
Solving for 'x' we have:

So, the solution to the system of equation is: (37.5, -30)
Answer:
35) 5/12 36) 7/11
Step-by-step explanation:
Because, when you are drawing a girls name from the hat, the probability would be 7/12, then you replace her name and that would make the probability to draw a boys name 5/12. (since you replaced the girls name before.
now you have a probability of drawing 5/12 for a boys name, and now you don't replace the name, so the probability to draw a girls name out of the hat, would be 7/11
(idk if you have to put both answers on one, so if so, then do that for your answer Example: for 35, if the answer is 5/12, 7/12 then do that
Hope this helped, sorry I am not good at explaining things:)
