How are the environmental dangers that face the region related to its geography?

Since the most modern techniques of farming are used to fulfill the growing demand, widespread use of chemical fertilizers and pesticides are used. So a lot of toxins get accumulated in the soil owing to its degradation. This is one the major reasons for environmental degradation.

i would say that the politicial parties from state to state varies.

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
