If you meant to write 6 + (1 + 4) = (6 + 1) + 4, then the property being illustrated is that of associativity.

.

As x → 0  e^x →  1 + x,  e^-3x →  1 - 3x, so 3e^x - 2e^-3x - 1 → 3(1+x) - 2(1-3x) - 1 → 9x

Also, -3x - x² +x³ → -3x

So: (3e^x - 2e^-3x - 1)/(-3x - x² +x³) → 9x/-3x → -3

» What is the property of the following equation?:6+(144)=(6+1)+4
The most obvious property is that it's false! 

That would look aweosme then Melody!

Try this unit

$$\\905=\frac{4\pi r^3}{3}\\\\
\frac{905*3}{4\pi}=r^3\\\\
r=\left(\frac{905*3}{4\pi}\right)^{1/3}$$

And you can finish it :)

You cannot put them on a number plane you can only put them on a number line.

look here

$$\\\frac{n}{62.5}=\frac{656}{100}\\\\
n=\frac{656}{100}\times 62.5$$

Now you can finish it.  

3x² - x - 4 = (x + 1)(3x - 4)

Melody, your initial logic (the use of v² = u² + 2as) would work if you imagine the car going straight up:

Thanks Roasla.

I want the Sydney version of that apartment - that would be fantastic!

Well

$$e^{(x+y)}=e^x*e^y$$

Write an expression for the n^th term of the sequence, 6, -2, -10, -18….

$$\boxed{a_n=a_1+(n-1)*d}\\\\
a_1=6 \small{\text{ and }} d=-8 \\\\
a_n = 6 + (n-1)*(-8) \\
a_n = 6 -8n +(-1)*(-8) \\
a_n = 6 -8n + 8 \\
a_n = 14 - 8n\\
\boxed{a_n = -8n + 14 }$$

So $$\textcolor[rgb]{1,0,0}{B)}$$ is correct.

PEMDAS ---> Parenthesis, Exponent, Multiply, Divide, Add, Subtract

9 / 16 = 0.56 x 100 ----> 56%

your welcome, study hard x

I hope that you realise happy - your answer is an approximation.  It is not exact :)

You are learning to use the calculator very efficiently - well done :))

There are 35 rabbits and birds combined in one cage. There are 94 legs in the cage. How may rabbits and how many birds are there?

$$\begin{array}{lrcrcl}
(1)& \quad \small{\text{ rabbits } & +& \small{\text{ birds }} &= & 35 \\\\
\hline \\
& \quad 4* \small{\text{ rabbits } &+& 2* \small{\text{ birds }} &=& 94 \quad | \quad :2\\\\
(2) & \quad 2* \small{\text{ rabbits } &+& \small{\text{ birds }} &=& 47 \\\\
\hline \\
(2)-(1): &2* \small{\text{ rabbits }-\small{\text{ rabbits } &+& \small{\text{ birds }} -\small{\text{ birds }} &=& 47-35\\\\
&\small{\text{ rabbits } } &+& 0 &=&12 \\\\
&\small{\text{ rabbits } }&& &=&12
\end{array}\\
\boxed{\small{\text{ rabbits } } =12 } \\
\begin{array}{lrcrcl}
(1) & \small{\text{ rabbits } }&+& \small{\text{ birds }} &=& 35 \\
& 12 & + & \small{\text{ birds }} & = & 35 \qquad | \quad -12 \\
& & & \small{\text{ birds }} & = & 35-12 \\
& && \small{\text{ birds }} & = & 23
\end{array}
\\
\boxed{birds = 23}$$

That is very funny.  

Are you really contagious Cue?  Don't worry because I don't think that you are.  Besides you really do not have CDD so you cannot transmit it to me.    

Don't wipe the smile of your face either - I like your smile  :)   

Maybe I caught it off Nauseated.  He probably has not truly gotten over this disease and he is probably still a carrier too.   

wolfram alpha often gives the answer in a number of alternative forms, so choose whichever one looks best to you!

Once you work it out for yourself, you can check your answer at wolfram alpha

Which program????

Standard deviation is a measure of variablity.

If there is no variation between samples, then S.D. = 0

The greater the differences, the greater the S.D.

Trig is an exciting area of maths to study. It deals with geometric shapes, their areas, sides and angles, and the relationship between these. If you know Pythagoras's Theorem, then you have already started on trigonometry without knowing it!

Is it 3x^2 - x - 4?

If so, there is not what you'd call a neat solution.

Maybe you mistyped it? Please check and confirm!
