6+4=210       6-4=2   6+4=10

9+2=711

8+5=313

5+2=37

7+6=113 

9+8=117

10+6=416

15+3=1218

?+?=48                

6+2=48

the answer is (1/2)π2R4

in a rectangular garden the width is two feet less than length. If each dimension is increased by 3 feet what is the equation that represent the new area?

Let the original length be L

then the width will be L-2

Now add 3 to each of these.  That will give you the new dimensions

Multiply new length by new width to get new area.   it will be in feet squared :)

Have a go at it yourself, you can ask us if it is correct if you want to :)

Yes, they are exactly the same. 

Here's an example: 2-3=2+(-3)

2-3=-1

2+(-3)=-1

-1=-1, so 2-3=2+(-3) is a true statement.

what will this equal? 20 (radical) 3

\(20\sqrt3=\sqrt{20^2}*\sqrt3=\sqrt{400}*\sqrt3=\sqrt{1200}\\ also \;equals\\ 10\sqrt{12}\)

You can think of +numbers as hot numbers and -numbers as cold numbers. 

If you take away hot air out of a room will it have the same effect as adding in cold air?

What will happen with each of these?

I'm acutally trying to use the calculator to do n= 1.96 x 0.68 / .02 and then I take that answer and square that number.  I just don't know which button on the calculator it is.

Hit the "2nd" button......it's the "asin" key

Oh,

 To see the code, right click on the matrix, 

choose " Show Maths as "  

then choose  " LaTex commands"

Here is a little example of one.

To do this I clicked on the LaTex button in the ribbon.

I deleted the content that automatically come up, then I clicked on the matrices button.

I chose the square brackets.

If you want to learn LaTex so that you can do this type of thing, we can help you :)

\(\begin{bmatrix} 1 && 2 \\ 3 && 4 \end{bmatrix}\)

It means totally radical dude

(7/8) (-2/7) (-4/9)    note that we can switch numerators/denominators when we multiply fractions......this sometimes makes things easier........write this as:

(7/7) (-4/8)(-2/9)  =

(1) (-1/2)(-2/9)  =

(1) (-1/9)(-2/2) =

(1) (-1/9)(-1)  =

(1) (-1) (-1/9)  =

1/9

the awnser is 5

It means extraordinary, depending on how you're using it. Melody's answer was correct aswell.

(-4,-3), (1,4)

d = √ [(-4 -1)^2 + (-3 - 4)^2 ]   =  √ [ (-5)^2 + (-7)^2]   = √ [ 25 + 49]  = √74  = about 8.6  units

Rad stands for radians

You are used to measuring angles in degrees but they can also be measured in degrees.

360 degrees = 2pi radians

There is no apparent agreement upon this :

http://mathforum.org/dr.math/faq/faq.0.to.0.power.html

it is 0 you are right. But it says there's an error. Did you get that too?

0.333*3.14*9*4 = 37.64232

WolramAlpha gives the following possible [paired] integer solutions :

 ±158, ±59

 ±134, ±133

You can mix and match them however you wish to get the pssible values for a, b, c and d

I meant it. By the way that's not nice. I just had something where it wouldn't let me have normal users see it.
