Which shows the proper use of the distributive property
Karo-lina-s [1.5K]

Answer:

-2 (6x - y) = -12x + 2y

Step-by-step explanation:

By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y

I’m trying to help my little brother and idk how to do this
White raven [17]
In order to get an answer, you have to have the same denominator which is the bottom number of the fraction. 40 could be one. so you would multiply the top and bottom of the first fraction by 5 which would get you 5/40 and the second fraction by 4 so 28/40. so she can pour 23/40 glasses of milk
