Step-by-step explanation:
We are asked to find the altitude of the equilateral triangle whose perimeter is 18 . Firstly let us find the side of the∆.
Now we know that in a equilateral triangle , the altitude of the triangle with side length a is ,
Plug in the value of a that is 6 , we will get ,

(-2,2) and (-2,-3) are the bottom vertices, since (3,-3) is the top you can tell that it is the upper left vertex since it lines up with (2,-3), so the fourth vortex would line up with (-2,2) and would therefore be C. (3,2)

Step-by-step explanation:
Let
be the number of ounces of caramel that has to be added to each scoop of ice cream.
So,for
scoops,there has to be
ounces of caramel.
It is given that for every 5 scoops of ice cream,3 ounces of caramel has to be added.
So,
and 
For 8 scoops of ice cream,there has to be
ounces of caramel added.
But Freeze Zone adds 6 ounces of caramel.
So,Ari thinks that Freeze Zone adds more caramel
