14-(-4)=14+4=18

Multiply both sides by 8

Sqrt(4×16)=2×4=8

2 1/6 = 13/6   

48 x 13/6  =  {cancel the 48 and the 6}

8 x 13  =

104

People are very weird. 

People are very weird.

the species is incomprehensible.

Let the three numbers be 2n-1, 2n + 1 and 2n+3  ......so we have

(2n - 1)(2n + 1) + 34 = (2n + 3)^2    simplify

4n^2 - 1 + 34 = 4n^2 + 12n + 9      

33 = 12n  + 9

24 = 12n     divide by 12 on both sides

2 = n

The first odd number is 2(2) - 1 = 3

And the next two are 5 and 7

Z = 10

AS 10*10*10 = 1000 :)

6.4x + 2.8y = 44.4

6.4(3) + 2.8y = 44.4

19.2 + 2.8y = 44.4

2.8y = 44.4 - 19.2

2.8y = 25.2

y = 9

why hello, there! how are y'all doing this evening?

the answer is 0.0000000001

$${\frac{{\mathtt{2}}}{\left({\frac{{\mathtt{1}}}{{\mathtt{12}}}}\right)}} = {\mathtt{24}}$$

You can visualize this by determining that since 1 board is 1/12 of a meter, then it takes 12 boards to make a meter.

You have 2 meters, therefore you have twice as many.

You take the given x-value, in this case -4, and insert it into the function.
$${\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}^{{\mathtt{x}}}$$ becomes $${\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}^{-{\mathtt{4}}}$$, and you get your answer, $${\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)}^{-{\mathtt{4}}} = {\mathtt{81}}$$

Since the function is (1/3)^x , substitute -4 where the x appears, giving you (1/3)^-4.

I get 81.

5^^2/3*5^^1/3= 5^3/3= 5¹= 5

$${\mathtt{327\,000\,000\,000\,000}}{\mathtt{\,\times\,}}\left({\frac{{\mathtt{1\,000}}}{{\mathtt{1}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{1}}}{{\mathtt{9\,460\,528\,400\,000\,000}}}}\right) = {\mathtt{34.564\: \!665\: \!542\: \!360\: \!192\: \!1}}$$

Sorry, but I have not figured out scientific notation yet. The first number is the number of km you were given. The parenthesis is the conversion to meters, since the conversion factor that I found is meters to light-years.

So about 35 light-years.

You guys need to stop posting these, but the answer is 19.

Or if you mean sqrt(36), it equals 6.

2(wl+hl+hw)

Use the sine function to arrange the equation.

$$Sin\theta=\frac{6}{10}$$

To find the angle, remember that you will have to take the arcsin of (6/10).

Rational numbers can be expressed as one number divided by another number. Since 19+ sqrt(14) cannot be expressed this way it must be irrational. Like pi, it just goes on forever.

If you can rearrange the equation into the form y=mx+b, you will know that the graph will be a straight line (linear).

4x-2y=-8

can be rearranged into

y=2x+4

It is because of the order of operation. The () on the left is (4*5+8).

sqrt(28)* sqrt(7)=14

Holy p**p. I seriously just.. wow
