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.

How are the aquatic organisms, wildlife and the human population impacted by trash pollution?
Allushta [10]

Trash pollution like plastic can impact aquatic organisms, they can swallow the plastic which can kill them if not treated right away, other trash pollution like oils can make the aquatic organisms sick. Some pollutants can also affect the mother's milk when it comes time to feed their young, Lots of pollutions can make the animals sick very sick and they can't fight the virus so they ended up dying putting their species at risk of extinction.

Air pollutants can affect the birds, they are breathing in toxic airs from factories and that can kill them too or make them sick.

Pollutions are very bad for aquatic life and wildlife, we have to make sure we keep this planet clean or else we will die out too like the animals

hope this helped :)

Have a great day

Explain the seasonal precipitation pattern in bangkok in terms of pressure and wind systems. what causes the summer rains? what
marysya [2.9K]

Bangkok, the capital of the Southeast Asian country of Thailand, is influenced by the monsoons, and they are the dominant climatic factor in this region and gives it its climatic patters.

There's two seasons, a wet one, and a dry one. The wet season is characterized by heavy rainfall for a prolonged period of time, and those rains are brought by the wet and warm monsoons coming from east. The dry season is characterized by prolonged period of time that is warm and dry, and that is caused by the dry monsoon winds coming from the west.

During the wet season, the air pressure is higher because the rain increases the weight of the air.

During the dry season, the air pressure is lower because of the high evaporation, and the water vapor is lighter than the air itself, thus causing the air to weigh less.
