Answer:
6+12y
Step-by-step explanation:
first, distribute the 2 to the parenthesis:
-multiply the 2 to the 3 and 6y
We get 6+12y
hope this helps :)

Answer:
Step-by-step explanation:
a traingle because it doesnt use any rectangular faces it only uses traingular forms or even a speer a speer has no rectangular sides
3 times as much as the sum of 3/4 and 2/6
Check the picture below.
the distance from 1,2 to 1,8 is simply 6 units, we can read that off the grid. Now let's see what the other distances are, and add them all up to get the perimeter.
