Answer: 
Step-by-step explanation:
(
)/12
Divide the fraction by 12. This is because we need to split the sugar between 12 brownies, and to split something means to divide it. Use the switch, flip and multiply method.
I inserted an image on how to use this method.
Anyway, to use this method, we need 2 fractions, so instead of 12, we have to use 
.
= × 
Multiply the denominators and numerators
=
Y= 4x
I think that’s the answer
There's no way for me to do that, because my expression
is totally blank, and doesn't involve ' m ' in any way.
But if you'll come back and give us <u>your</u> expression, I'll
evaluate it for m=12, and I'll also show you how.

Break the expression into group:
factor out x from 4x² - 5x : x (4x-5)
factor out 3 from 12x-15 : 3 (4x-5)
factor out common term (4x-5) :
hope this helps!
