The answer with factoring is x^2 + 16x + 63

do you want to graph this?

Thanks for your answers. Alan's answer makes more sense to me, so ill go with his. 

If his anger doubles every 20 minutes, then, because there are 9 lots of 20 minutes in 3 hours his anger will have increased by 2⁹ or 512 times!

 I'll expand on the above a little:

After 20 mins (1*20mins) his anger doubles, i.e. increases by 2¹

After 40 mins (2*20mins) his anger has doubled again, total increase = 2¹*2¹ = 2² 

After 60 mins (3*20mins) his anger has doubled again, total increase = 2²*2¹ = 2³ 

After 1 hour 20 mins (4*20mins) ... , total increase = 2³*2¹ = 2⁴ 

... etc.

After 3 hours (9*20mins) ..., total increase = 2⁸*2¹ = 2⁹. 

16 times as angry?20 minuites equals twice as  so every 20 minuites multiple by the answer itself=        (2^,4^,16=3 hours)

OK....I just had to reduce my screen size....sorry!!

The other angle in the triangle is 90 - 17 = 73

So using the Law of Sines we have

10/sin17 = x / sin 73

x =10 (sin 73)/(sin 17) = 32.7 = the side opposite the 73 degree angle

Now just use the Pythagorean Theorem to find the hypoteneuse...

Sqrt (32.7^2  + 10^2)  =  hypoteneuse

I'll leave this for you to finish......just add all the sides for the answer!!

wait a minuite you took Chris's glasses too talking about me.....

again come on thats a real math question!!!! i didnt know that thought it was just a regular question and oh yeah almost forgot   

24

There are 4 ways to choose the first letter....3 ways to choose the second letter ......2 ways to choose the second letter.......and 1 way to choose the last letter

Thus......4 x 3 x 2 x 1 = 24

BTW......this is known as 4!    (4 factorial)

Hello! The answer is 10019.3565217

Hope this helps

As to 10......(I assume this is a trig class??)

We have

sin 50 = 20 / L      

L = 20 / sin 50 ≈ 26.1 m

As to 11....the image is "off the page," so I can't tell what you've got....try sending another pic!!

3x-2x+3 = 2+2x-2x

This line should be 3x-2x+3 = 8+2x-2x Melody.

OK

A = pi * r^2

So

314.2 = pi * r^2     Divide both sides by pi

314.2 / pi = r^2      Take the square root of both sides

√(314.2 / pi)   = r   = 10.00064829093329474 ft  or about 10 ft

$$Area = \pi r^2\\

314.2=\pi\times r^2\\

314.2 \div\pi =r^2\\

r^2\approx 100\\

r\:\:\approx 10feet$$

The value of x is always 2. Except when it isn't 2, in that case it's 2.

10 ft pi r^2

Good one Chris!  I like it. lol for real!

how about you Cassdy1 ?

did you get too many answers? - does that make it harder?

Press on the home tab at the top of the page and then put it into the calculator.

As it stands, you have not asked a question at all.

Maybe the minus sign was meant to be and equal sign like CPhill suggested

Maybe it was all supposed to equal 0 like anonymous suggested.

Maybe you were supposed to factorise it and then the answer would just have been 7(2c-3)

Who knows?  Not us!

It is good that you have tried to do it yourself!

3  x  + 3 = x + 1 + x + 2 + 5

I'll try to make it easier for myself by doing like this:

YOU ARE WORKING ON THE RIGHT HAND SIDE.

1+2+5=8  YES

x+x=2x     YES

8+2x=8x+2   NO  Think of a page - write the number 8 and somewhere else on the page put 2 crosses. 

is that he same as writing the number 2 and drawing 8 crosses. NO of course it is not.

3x +3=8+2x   YES

The idea is to get all the lots of x on one side and get all the numbers without xes on the other side.

Subtract 2x from BOTH sides

3x-2x+3 = 8+2x-2x      ERROR FIXED - THANKS ANONYMOUS!

x+3 = 8

now subtract 3 from both sides

x+3-3 = 8-3

x = 5

And if you have any questions, just ask.

We've just created a new math "identity"

1 question = "infinite" answers

Thus

1 = ∝

(And we have the "proof")

OK...good job, so far.....(we'll talk about one of your "steps" in a second)

So we have

3x + 3 = 2x + 8      Since I usually like all the "x's" on the left and everything else on the right, let's subtract 2x from both sides   We have

x + 3  = 8      Then subtract 3 from both sides    We get

x = 5  

And that's it  !!!

I don't know if this was a "mistype" or not, but in general

8 + 2x ≠ 8x + 2      (This only works if x = 1 !!)

There you go Cassdy1

I told you lots of people would want to answer your question.

Now the tough bit is choosing which answer you like best.

If you need more help to understand just ask.

You can say which answer you are referring to!

None of us will mind - we just want to help you learn.
