The correct answer is 9y + 3
Explanation:
The perimeter of a triangle can be find by adding its sides. This means to find the perimeter of the triangle shown it is necessary to add the three expressions given. Additionally, in this case, the expressions combine the letter y and regular numbers.
Due to this, the first step is to add all the "y" expressions and the numbers beside them, this means 2y + 4y + 3y = 9y, and then, the numbers remaining: +5 -2 =3. According to this, if the three sides are added to find the perimeter the final expression is 9y + 3.

Moctezuma I wanted to have everything under control in the empire, and also to put order in it and make a proper class system. This resulted in multiple reforms in the political, social, and economic spheres. Politically, Moctezuma I managed to form the Triple Alliance, managing to make an alliance with two other empires, sharing the land, resources, and rule, while maintaining the dominant power in it. He established himself as the absolute authority, so everyone had to notify him of everything that was considered important and he had to give permission for it to happen. Socially, he created the classes, setting up rules which people can be in what class, what kind of homes can they have, what objects they are allowed to visit, but also forbid mixing of the classes. Economically, he created aqueducts and much better developed agriculture and usage of the natural resources, while also developing the trade.
