Find the root of the following equation: (6+x)2−x2=168

Answers

Answer:

No solutions (roots)

Step-by-step explanation:

The root of an equation is basically the solution of the equation. If I'm reading the problem correctly, the equation is (6+x)*2 - x*2 = 168.

We distribute the (6+x)*2 part and get 12+2x - 2x = 168. Uh oh.. the 2x terms cancel each other out and we are left with 12=168. Either I'm reading the equation wrong or the equation has no solutions.

Find x and y intercept and graph -3 + 2y = -5

Answers

x intercept = none
y intercept = -1

Answer:

( [tex]\frac{5}{3}[/tex] , 0 ) ; ( 0 , - [tex]\frac{5}{2}[/tex] )

Step-by-step explanation:

- 3x + 2y = - 5

Coordinates of x-intercept are (x, 0)

- 3x + 2(0) = - 5 ⇒ x = [tex]\frac{5}{3}[/tex]

Coordinates of y-intercept are (0, y)

- 3(0) + 2y = - 5 ⇒ y = - [tex]\frac{5}{2}[/tex]

3. Solve for a
5(a-2) = 2(10+a)

it’s due by midnight and can you also tell me how you got the answer

Answers

Answer:

a=10

Step-by-step explanation:

distribute on both sides to get

5a-10=20+2a

add/subtract like terms

5a-2a=3a

20+10=30

so the equation is

3a=30

divide 30 by 3 and you get 10

Answer:

a = 10

Step-by-step explanation:

[tex]5(a - 2) = 2(10 + a) \\ \\ 5a - 10= 20 + 2a\\ \\ 5a - 2a= 20 + 10\\ \\ 3a = 30\\ \\ a = \frac{30}{3} \\ \\ \huge \red{ \boxed{a = 10}}[/tex]

Answer:

Step-by-step explanation:

so  49.8004 is what it is 0.001 left. 1  x or divide it stay the same

exp: 1[tex]1\sqrt{2}[/tex]

Explanation:

Whenever you divide by a fraction, you multiply by the reciprocal of that fraction, so 49.8004 / 0.001 would be 49.8004 / 1/1000, which would be 49.8004 * 1000/1, which is 49,800.4.

If you think about it, the problem translated into words is "How many 0.001's fit into 49.8004", which is a big number, because a lot of 0.001's can fit inside 49.8004.

PLEASE HELP i want to know if this essay is good enough for me to submitDid you know that adding too much greenhouse gases makes the earths atmosphere too warm that it puts animals and humans in danger. There is a blue lining around the earth called earths atmosphere, and that blue protects us from the suns harmful rays, keeps us from freezing during the cold seasons, and protects us from space (as you may know space does not have oxygen to where humans can breath normally). Wait what was that.. What can you do to stop adding greenhouse gases to the earth? Well thats exactly what I am going to educate you on. So just sit back and pay attention.So as I said adding too much greenhouse gases puts animals and humans in danger. I know what your thinking. How bad can greenhouse gases be to put animals and humans in danger. Actually, it is so bad it adds heat to the earth and even when its hot enough already. Every year it feels hotter and hotter in the summer. Thats because humans are adding the greenhouse gases to the earths atmosphere. In fact, most humans are adding greenhouse gases to the atmosphere without knowing it. If you think about it, the bigger our population: the more resources we need to live. One of the biggest resources humans need to live is energy. Most of the things we use everyday uses energy. For example: light, cars, cell phones, computers, TVs, and video games. There is more than that but that is all I can think of for now. The greenhouse effect is a natural process that causes the earth to warm up. This process involves the sun and many gases in our atmosphere.Our energy comes from fossil fuels, which is oil, coal, and natural gas. Fossil fuels are an important resource for energy. Fossils are formed when plants and animals die and are covered in sediment and pressed for many thousands of years. Climate change is very dangerous. That is why I need to explain to you what you can do around and in your home to help stop global warming. Global warming is a process that is caused by fossil fuels, greenhouse gases, and the greenhouse effect. So listen carefully if you are interested in knowing how to stop global warming starting with you. The biggest factor of climate change is the use of energy which as I said is made from the burning of fossil fuels. So when you are at home and a light or the TV is on and it is not in use it would be a big help to turn it off and conserve energy within your home. Carbon dioxide is a harmful gas to humans and animals so planting some trees or flowers also helps a lot. When you are driving it adds more greenhouse gas because you use fuel to fill up your tank, so using a public transportation or riding a bike will help more than anything else when you are outside. When you are in the kitchen cooking (I know even cooking adds greenhouse gases to the earth) using a toaster or a microwave to cook some food will save much more energy than using an oven . Another big way that energy is used within your kitchen is a dishwasher. Dishwashers use a lot of water and produce a lot of heat, so hand washing a drip drying your dishes is a much more easier way to save energy. And last but not least when your at school recycling stuff that can be recycled instead of throwing it away is also a way you can help stop global warming. Making sure the computers you use in your classroom are all off or on sleep mode when not in use is a even better way to help in school. But the most helpful when trying to help stop global warming is riding your bike or skateboard to school instead of asking your parents for a ride. So I hope you enjoyed my essay and remember helping stop global warming is a good deed many people dont think of. Save energy the best you can and have a wonderful day! 12.
