The soviet union's security strategy was a reaction to o open threats from neighboring countries. the devastation it experienced in world war ii. o emerging economic issues within the country. the ongoing threat of immediate attack.

the devastation it experienced in World War II

Explanation:

The Soviet Union was one of the most damaged countries because of the World War II. Tens of millions of people were dead because of this war, so understandably, the government quickly developed security strategy for the future in order to avoid such devastation again. This strategy was mostly focused on two things, heavily investing in the military, and making as much allies as possible, especially countries that were surrounding the Soviet Union so that they can act as a barrier.

B ~ The devastation it experienced in World War ll

Explanation:

Just took the quiz it’s correct ;) !

idk

explanation:

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
