Could you list all of the answers, please? HURRY TOO. I'M DESPERATE... TvT

1. Earth's climate has changed throughout history. In the last 650,000 years there have been seven cycles of glacial advance and retreat.

2. Changes in the sun's intensity have influenced Earth's climate in the past. For example the ice age, it could have been partially the low solar activity phase.

3. Climate change as we know it today is characterized by an abrupt increase in the Earth's temperature.

4. Over the last century, the average surface temperature of the Earth has increased by about 1.0 degreeF.

5. (If you have a article or something that maybe states it, try there but the hottest decade is 2009- 2021)

6. Multiple studies have shown that at least 97 percent of scientists agree that global warming is happening and that human activity.

7. Carbon dioxide, methane, water vapor, and nitrous oxide

8. Greenhouse gases trap heat in the atmosphere

Explanation:

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

answer; the best answer is (demand);
