Answer:
calculate the distance between the 2 points, then multiply by 4 to get the perimeter
d^2 = 2^2 + 7^2 = 4+ 49 = 53 distance squared = sum of the squares of the differences in y values squared plus difference in corresponding x values squared. 7-5 = 2 4--3 = 7 2^2 =4 7^2 = 49
d = sqr53 = about 7.28
Perimeter = 4sqr53 = about 29.12

Milky Way is a elliptical galaxy. Galaxy,
by definition, is an arrangement composing of stars, planets, gasses and
everything more that can be seen in the space. There are three types of

<u>Answer:
</u>
The build-up of three oxygen created our ozone layer around two billion years ago.
<u>Explanation:
</u>
- The ozone layer is a part of the stratosphere which is located right after the troposphere in the atmosphere of the Earth.
- The ozone gas is made up of the abundance of three oxygen molecules combining with the ultraviolet radiation emitted by the Sun.
- The development of the ozone layer happened around two billion years ago when the oxygen concentration levels on the planet began to rise slowly and gradually.
