We have all noticed that if we hike from a place with low elevation and go up at a place with high elevation, that the temperature is gradually dropping, thus giving us a clue that the lower places are warmer, while the higher places are cooler. The reason for this, even though both the places with low and high elevation are located in the troposphere, thus the same atmospheric layer, is that the density of it is not the same everywhere. The troposphere has the highest density at its lowest points, and as the height increase the density decreases. Since the higher parts are less dense, that means that there are less gases, thus there are less molecules that are further apart from each other. This results in lesser absorption of heat, so this parts are cooler, while the lower parts are warmer because the troposphere is denser, there's more molecules that are also closer to each other, thus they absorb more heat.
Well if the base of the building is stronger there could be a great chance that the building wont just collapse.
Answer:
Explanation:
x to the 2nd power plus 3x-4
x to the 2nd power minus 2x-8
1. The dividing out method my seem like the thing to do but really you to to combine like terms on the top and the bottom so the top an the bottom should become 3x to the 2nd power plus (-4) over 2x to the 2nd power minus (-8) since you can only divide 3x to the 2nd power and 2x to the 2nd power your answer would become 3-4 over 2-8 because both x to the 2nd power cancelled each other out now minus the top and the bottom and the answer would be -1 over -6
2. for example (4)(6) over 4 plus 6 it would be hard to divide this because you the top and the bottom equations have not been solved yet, but when you do solve them your answer would be 24 over 10 but you cant divide these evenly and when you do try to divide them you would get a decimal or 2.4 also your answer word be an improper fraction 24/10 which could change into 2 4/10nso i don't think is would be easy to divide in order not to make this mistake always make sure both the top and bottom equations are solved and make sure you can divide them
3.a one thing i always remember is the equation solved yet i so can i divide
3.b What is the dividing out method can it be used for the following equation (3+4x) to the 2nd power over (4-2x) to the 2nd power.
