Thomas Paine argued in the common sense that the independence of the 13 colonies was necessary.

Explanation:

Common sense, The Rights of Man and Dissertation on the First Principles of Government reveal the power of Thomas Paine's words - one of the most eloquent advocates and signatories of the Declaration of Independence of the United States and the French Revolution.

These writings played a central role in the struggle for American independence and in the democratic revolution that swept the Western world in the late eighteenth century.

Paine gave new and modern meanings to words like "republic", "democracy" and "revolution" while establishing a vision of America as the haven of democratic freedom. A deep believer in the people's political influence, Paine was the first great speaker to address a mass audience. Two centuries later, his words are still remarkable for their vigor, clarity, and ability to inspire.

30 and 44 are b

explanation:

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
