Answer:
-85
Explanation:
Given the mathematical expression:

First, we recall the product of signs.

So, first, we open the bracket:

We then simplify:

The result is -85.
(5x^2-15x) (-2x+6)
5x (x-3) -2 (x-3)
(5x-2) (x-3)
Hopefully this helps and makes sense to you if you don’t understand ask another question to me or anyone hehe
yes and no answer+the math:
1) yes
2) yes
1) so if you take 255-75 you get 180 now keep that in mind for number 2, when you divide 180 by 6 you will get 30 so we can give 30 cards to everyone
2) remember the 180? were using it again. if you do 180 and divide that by 4 you get 45 so we can give 45 cards to everyone.
hope this helps!
