What event inspired Francis Scott Key to write “The Star-Spangled Banner”? A. the end of the War of 1812 B. seeing the American flag flying above Fort McHenry C. the surrender of the British fleet D. the American victory at the Battle of New Orleans

B, Seeing the American flag flying above fort McHenry

Explanation:

The Star Spangled Banner is based off of the battle of McHenry, lines like "the bombs bursting in air" confirm it was indeed a battle. It was created when Francis Scott Key was watching the battle from his window, and he was focused on looking at if the flag was still there. Originally the Star Spangled Banner was called The Defence of Fort M'Henry

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7
