When you get x by itself, meaning it is laid out like this: x=7

Then you should look to the right of the equal (=) sign. 

Now you have your answer! :D

Let's measure in km.

20*31557600*20000000000 = 12623040000000000000​

So it is 12623040000000000000​km and it keeps growing.

As for how old you are, I'm guessing 8.

Cards all the way

Heii.....

No need to be an a*s! Have some sympathy!

ugh i do not care

Depends on the problem, I usually just divide.

Hope you get better soon. My mom has been sick for 3 months and I am worried

But I hope your sore throat becomes ....ummm whats the opposite of sore?

Yeah I know the feeling 

Packers! I like the Cardinals too. But Packers more!

Doing the 3.142 x the measured diameter of Earth (12752.2 Kilometers) gives 40079.9804 Kilometers

Perimeter is the length around the whole box. If the lengths are 8 feet, you have 8 feet on two sides which is 16 feet. That means you have to subtract 16 from 34 and divide your answer by two since you need the other two sides. That will give you your width.

The perimeter of a rectangular sandbox is 34 feet.If the length of the sandbox is 8 feet,what is the width of the sandbox

L = length 

W = width 

P = perimeter

\(\begin{array}{rcll} P &=& 2\cdot L + 2\cdot W \\ 34 &=& 2\cdot 8 + 2\cdot W \\ 34 &=& 16 + 2\cdot W \qquad | \qquad - 16\\ 34-16 &=& 2\cdot W \\ 18 &=& 2\cdot W \qquad | \qquad :2\\ \frac{18}{2} &=& W \\ 9 &=& W \\ \end{array}\)

The width of the sandbox is 9 feet.

What is the solution of 19.3 g/cm3 * (100cm/m)3 / 1000 g/kg

density

 \(= 19.3\ \frac{g}{cm^3} \cdot \frac{100\ cm^3}{m^3} \cdot \frac{kg}{1000\ g} \\ = \frac{19.3}{10}\ \frac{kg}{m^3} \\ = 1.93\ \frac{kg}{m^3} \\\)

You take the 1/4 and muiltply it by -6 that add it with the -1.
