Answer:

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.

sattari [20]

Answer: B - help map the ocean floor

Explanation: GPS which is an acronym for Global Positioning System is a global satellite based location and navigation system owned by the US Government. It was first used by the US Air Force in 1978. It's main purpose is to show a GPS user location and time information from anywhere on earth, where there is an unobstructed line of sight from the precise location to 4 or more GPS satellites. GPS is commonly used on land (obviously through every day use like when you use an uber) and in the air (pilots use GPS signals when they fly).

GPS can be used to track pets if there's a tracking device on their collars.

GPS is also used in taxis and can be used to track a cab after a hurricane.

Ordinary people can use GPS to collect information for scientists - an example of this would be taking a new undefined route on Google maps therefore adding to their archive of known routes/areas.

However GPS signals cannot penetrate water - sea water especially. Hence the answer is B

Anyways, the answer is simply to find.
First make sure the units are the same.
Secondly, subtract the first sphere number by the second.
The answer is 35 cubic in.

Hope I helped!!! :)

How are edge cities formed and how are they beneficial/detrimental?

sergey [27]

Hey there! I'm happy to help!

Edge cities are usually formed because land in the suburbs or on the outskirts of the city is cheaper (bid-rent curve), so they can make more a profit.

These businesses are normally connected the the CBD (central business district) so transportation to and from that area is still possible.

People that live in the suburbs or are visiting the main city have easy access to the edge city as you might not have to travel as far to these cities as the CBD (distance decay).

Edge cities can be a good thing because they allow for new businesses to thrive and they can increase economic activity and competition due to new construction, cheaper prices, new companies moving in, etc.

However, they can also be a detriment to the CBD because they might allow companies to relocate due to the cheaper land prices, they might take in the typical customers of the CBD companies, ultimately leading to the vacancy of the CBDs, which could be dangerous and create high-crime, unsanitary, or contaminated areas. It can also take attention away from significant or historical monuments and locations in the CBD.

Have a wonderful day and keep on learning! :D
