Answer:
720
Step-by-step explanation:
I will use the following counting principle:
Product rule: if there are n ways of doing something, and m ways of doing another thing, there are n×m ways of doing both things.
First, we have to choose the 3 people that will be in the first row. This is a 3-element subset of the set of six people, therefore there are 
ways of doing this.
Now, we have to arrange the order of the 2 lrows. Each one has 3 people, so there are 3!=6 ways to form one rows. Hence, there are 3!²=36 ways of arranging the two rows.
By the product rule, there are 20×36=720 ways of arrange the officers.

I wish i could help you but i only speak english can u translate this for me?
Answer:
I think we can easily see equilateral triangle. That means triangle will have all equal side. So we can arrange equation with this.
8 = 2x-5
8 = y+3
Use algebra to solve first 13 = 2x. x = 6.5. Now we do same on other, 8-3 = y
5 = y.
Therefore answer is
<h2 /><h2><u>
X = 6.5</u></h2><h2><u>
</u></h2><h2><u>
Y = 5</u></h2><h2><u>
</u></h2>
:)
X would be -2 to the second power
-2*-2^2 would give you 8 and 8-8 gives you 0
