Which expression is equivalent to the given polynomial expression?

Geography
1 answer:
EleoNora [17]2 years ago
5 0

Answer:

D

Explanation:

you have to make groupes.

start with a² part and forget the rest from example.

-4a²-a²=? Now remember - and - is adding up. so -5a², which takes out options a and b, as there are 3a² instead of 5.

now let's take ab part and forge the rest.

-2ab+6ab=? that gives us 4ab. So option c, which says 8ab, is wrong. the last number isn't really important in this case because you've already seen the rest can't be.

Earthshine is illumination seen during which phase of the moon?
Slav-nsk [51]
Earthshine is even more faint because the moon's "albedo" (a specific kind of reflectivity) is less than Earth's. Even though this dim light is only a reflection it can still illuminate some features of the moon. Earthshine can be best seen during the crescent phases (the 1-5 day period before or after a New Moon).

How does pollution effect the water cycle?
garik1379 [7]
Water cycle is effected by pollution, whether it is water pollution or air pollution. Air is polluted by Suspended Particulate Matter and by different harmful gases like Sulphur dioxide etc. These gases react with water vapours in the sky, making the water in the clouds acidic. This acid falls as rain water causing acid rains. This acid falls in ponds, on land, in fields, causing harm to us and to the crops as well as to the fishes or creatures in water. When the water evaporates from ponds, rivers and oceans to make water vapour, the the water in these water bodies becomes more acidic, and again when acid rains occur, this acid again mixes with the water of the water bodies, which already has acid, causing the water to become more concentrated.
