Answer:
l = 14
Step-by-step explanation:
The perimeter of a rectangle is
P =2(l+w)
The width is x-6
w = x-6
The length is 8 units longer than the width
l = w+8
l = x-6+8
l = x+2
We can substitute this into the equation for Perimeter, which is given as 40
40 = 2(x+2 + x-6)
Combine like terms
40 =2 (2x-4)
Divide by 2
40/2 = 2/2 (2x-4)
20 = 2x-4
Add 4 to each side
20+4 =2x-4+4
24 = 2x
Divide by 2
24/2 =2x/2
12=x
We want to know the length
l = x+2
l =12+2
l = 14

What is the process called when an Igneous rock can become a Metamorphic or Sedimentary rock called? Explain your thinking
What are some possible ways these rocks were formed? Be sure to discuss all 3 rocks.
pls help me
The brownish rock is a sedimentry rock was formed when things like sand, mud, or pebbles get laid down in layers. Eventually the layers are lithified.
The grey rock is a metamorphic rock and was when other rocks are changed because of heat or pressure. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure. They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks.
The red dots rock is an igneous rock. Igneous rock forms when hot, molten rock crystallizes and solidifies.
How does this simulation demonstrate the Law of Universal Gravitation?
Answer:
The Law of Universal Gravitation states that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. This simulation uses the sun to attract other planets. The greater the distance between the objects the greater gravitational pull.

what type of events might cause many organisms to die in the same area
Answer: Well first lets define "extinction event" which is a widespread and rapid decrease in biodiversity on Earth. Events that cause this is recognized by a intense change in the unlikeness of multicellular organisms. So basically it takes place when the rate of extinction increases with regard to the rate of speciation.
Explanation:
When life forms have limited geographical range, they are more likely to become extinct because many individuals may encounter chance events that harm the population, such as droughts, floods, the negative effects of invasive species, or rainforest deforestation.
What is an biodiversity?Biodiversity refers to the variety of life forms found in one area, including animals, plants, fungi, and even microorganisms such as bacteria. In ecosystems, all of these species and organisms coexist.
Biodiversity refers to the natural world around us and the variety of organisms such as plants, animals, insects, and microorganisms that live on our planet.
Every one of these exists in delicate balance and lives and works together in ecosystems to sustain and support life on Earth.
Because many individuals may actually meet chance events that harm population, such as droughts, floods, detrimental consequences of invasive species, or rainforest deforestation, life forms with limited geographical range are more likely to become extinct.
Thus, these are some of the events that might cause many organisms to die in the same area.
