The best answers are "A" and "E"

A: The Greeks attacked Persia because Darius captured Sparta's king.

E: The Spartan king, Leonidas, saved Greece by delaying the Persians at Thermopylae.

Explanation:

King Darius wanted to conquer the entire Greek occupied territory. The reason for the war was the aid that Athens provided to rebelling Greek cities of Ionia, Asia Minor (499–493 BC) which were under the rule of the Persian empire at the time.

Leonidas decided to sacrifice himself and his men in order to give enough time for the rest of the army to flee.

after the roman empire, the catholic church began to unify by taking on many duties of a government.

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
