Why might king have gone into such specific detail about steps taken and recent events in birminghham this early in the letter

Because he thought that it is better to ensure that people understood the main reasons why Martin and the other parts of the movement did what they did.

Explanation:

In writing the letter, King tried his best possible to explain the main points why he drafted the letter. He wanted to share the vital information about Martin and the movements by others with the public to ensure that they understood the main reasons why they performed the specific actions. Thus, he put the main points in the beginning of the letter.

roosevelt believed that in light of the country's recent military successes, it was unnecessary to use force to achieve foreign policy goals, so long as the military could threaten force. this belief, and his strategy of “speaking softly and carrying a big stick,” shaped much of roosevelt's foreign policy.

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
