**Algebra/Language Arts**

I have a 15 page paper due tomorrow. I finished the paper, and edited it and all, that's not my problem. My cover page is a work of art that I designed and I wanted to put a note on how it relates to my essay. How would I go about doing this? Do I add a page at the back af...

**Algebra**

1 and 2 are correct, as far as I can figure out. You would leave number 1 as 2.5, if not a more complex decimal. As a mathmatician, you will always show the decimals to several points out. Scientists don't like this saying that extra decimals just create confusions. If you...

**Algebra 2**

Oh! I get that now! Thank u soo much!

**Algebra 2**

Ya, but one is x^2=14x+5

**Algebra 2**

Ya I figured those out, but I put down your equation into my notes cause it made more sense than what I did. How do I factor with -x?

**Algebra 2**

2x(3x+4)-3(3x+4) -2x(x+7)-(x+7)

**Algebra 2**

Wait I got it! (3x+5)(4x-1). I have a few more...

**Algebra 2**

I got the third one (3x-7)(3x+2) but I can't figure out the 4th one. How do I do this that one? I know it can only be 5 and 1, but I tried all of the x values and it doesn't work! I tried 6 and 2, 12 and 1, and 4 and 3

**Algebra 2**

Factor each quadratic equation: 8x^2+10x-3 25x^2+10x-3 9x^2-15x-14 12x^2+17x-5 I don't get how to even start these! Help!

**Geometry**

Graph it out and use the Pythagorean theorem to find 2 sides. Multiply those together.

**Math**

I am not sure what the formula is, but I can tell you that 1/4 multiplied by 80 is not 60. It would be 20. 60 is 3/4 of 80.

**Writing**

Ok thanks!

**Writing**

No. I am supposed to use a quote as my title.

**Writing**

If I use a quote as a title, do I capitalize every first letter in the quote? Example: Should my title be... "The only place success comes before work is in the dictionary" or "The Only Place Success Comes Before Work Is In The Dictionary" please answer soon!

You cannot simplify this equation unless it is equal to something

What is do the numbers around the equation mean? Are they part of it?

Mrs sue put the equation for a interest that was put to the initial price and collected annually, this is not what the question is asking for.

**dhs**

8,500$ car, wow So if the interest rate is 4.6% for 5 years, she has to pay that percentage of the total cost each year. There is an equation for this, but to make it simpler ill tell you it this way: 8500 Initial cost 8500*1.046 cost after 1 year =8891 8891*1.046 Cost after 2...

**inequality/math**

3x-8>5 So 3x>5+8 3x>13 x<13/3 x<4.3333333333(forever)

**business math**

So first 50000000 times .8 which is the opposite of 20% which gives you your first answer of 40 million left over. The equation for the interest after this is 40000000(0.7^30)

**Spanish: check answers**

You are correct as far as I see, and the fast food question, you are correct, just usually the menus are a lot different

Ok, so I have this worksheet due, and it's for a lot of points, so can you check over my answers please? Can you leave your email so I could forward the scan to you? The worksheet has a lot of labeled shapes, so it's hard to describe in text. These are the answers that...

Jack-5=John See if that gets you anywhere, you need to do substitution.

3592736 is wrong. 461592*308=142170336. Then the final answer should be 156118096

Um, those fractions are in their simplest forms.

**Math**

So 2/5 of the stamps are left with 12 stamps. So there for 1/5 of the stamps is 6 stamps. Now just multiply 6*3 for the amount that he sent. =18

**algebra**

C(x)=70x-1000

**7th Grade Math stuffs**

Yes, as long as the equation is not rationalized.

**7th Grade Math stuffs**

Independent is by itself. Dependent needs a problem before it.

**Computer (Hardware Support)**

Um computers transformers and anything with a USB port.

Never mind everyone. I graphed it and showed him I was correct.

Just really quick, my friend and I disagree on this problem. I got 1997 and he got 721.033 4. A surveryor is standing on horizontal ground level with the base of a skyscraper. The angle formed by the line segment from his position to the top of the skyscraper is 31 degrees. Th...

**Math**

Plug the equation in in separate parts. Otherwise most calculators would change the steps up. Try this to start (8/(2^3))-2+(4.1*2). Remember the steps in solving an equation (power, parentheses, multiplication, division, addition, subtraction. In that order).

**math help me plss**

1c 2a 3(you need a percentage to start with) Converting percentage to decimal is easy. First get rid of the percentage sign by crossing it off. Then move the decimal 2 places forward. Here I did an example following these steps below. 27% 27 2.7 0.27 Just that easy! Really it&...

Eric, this really depends on if the block is porus. Could you please respond back with more details? I am willing to help. Also, what is the surface tension of the water?

**multiplying and significant figs**

Hmm, does your teacher want a specific decimal place? If so, you just tell the numbers as they calculate out to that decimal place (ie 0.284926493 if asked for ten thousandth place would just be 0.2849).

**multiplying and significant figs**

That is 2808, but let me show you how to easily calculate this out. For an example, 1507*1.93. If you plug this into a calculator you get the answer of 2908.51. Significant figures are just simplified numbers that engineers use. Since there is no machine that can go to such ex...

For the first part, it is just asking for a life cycle in math terms. A plant will grow a lot more in its first week than in its second third and so on. It's decay is 2x faster than its growth. For the second part, just ask your fellow students.

**Geometry**

This problem has some missing information. You know that the pole is 16 feet high, and the wires connect 12 feet up (16-4=12). If you found the length from the bottom of the pole to the grounding point, you could use the equation 12^2+X^2=L^2 with x standing for the length of ...
