Ответ:

Всё просто.

Объяснение:

1. 2(x+x+14)=88

2x+2x+14=88

2x+2x=88-14

4x=74

x=74:4

x=18,5 - 1 сторона параллелограмма.

2. 18,5+14=32,5 - 2 сторона параллелограмма.

3. 2(18,5+32,5)=88 - всё верно.

The United States allows a great deal of power to the individual states. Each state has a constitution, patterned after the national Constitution, with its three divisions of power: legislative, executive and judicial. The head of each state is the governor. Each state has control over its state government. But no state may pass a law contrary to the Constitution or to the United States’ laws and treaties. The federal government keeps control over foreign relations, interstate commerce, defence, etc. Each state creates units of local government. It outlines the pattern of cities, towns and school districts and so on. Large cities have an elected mayor as head of the elected council to help him. The mayor and council have broad power. The mayor-council system is the most popular kind of local government. The elected council keeps the legislative power. A city government must keep its people protected by maintaining a police department and a fire department. Large cities have health departments, libraries and airports to serve their citizens.
