when you square a number you multiply it by itself.
for example: 3 squared = 3 times 3 = 9, so 3 squared = 9

you are correct

working through it backwards because of order of operations:
3^2 = 3*3*3 = 9
2pi*9= 18pi
24pi + 18pi = 42pi

sorry teach, were doing as much as we can

its actually 30

ok heres how id do it

x+5+(4/x) = 0
subtract 4/x from both sides
x+5=-4/x
multiply both sides by x
(x + 5)x = -4

distribute

x² + 5x = -4
think about it for a moment and realize that the only way to get -4 is for x to be negative, but if its too big the x² will be too big for 5x to bring it down to -4. now to guess at some numbers because its late and im tired

-1² + 5(-1) = -4

1 - 5 = -4

bingo

x = -1

solved like a pro

im sorry im terrible at math

533/61 simplified is 41/47

you would know

25+5=84758475163516546458415613223146546521321321465465233215

C(7, 4)  = 35

there is a proper formula but i happen to not know that formula, so i figured out an easy way to do it.

to find the midpoint you just do (x₁ + x₂)/2 for the x value and (y₁ + y₂)/2 for the y value.

the answer is (5, -3)

the reason this works is because the midpoint between two points is always going to be halfway between each x and each y, otherwise itd be a pretty sloppy mid point. the mid is short for middle, so if it isnt in the middle, its not a midpoint.

somebody else should get the right formula in here though

10. (1+1+1+1+1)+(1+1+1+1+1)=ten ones

What? Next time actually write something that makes sense

Sorry but the guy above me is incorrect. The answer is actually x=1.5 thankyou very much and goodnight. Now I can have the cool shades on

5x5x5=125

5^3=125

We have

2x / 6  = x      multiply both sides by 6

2x = 6x          notice that the only value that solves this is when x = 0

This was answered here.....

Let x be the first number and 4x the second.

So we have

x + 1/(4x)= 5/12    mutiply both sides by 4x

4x^2 + 1 = (20/12)x

4x^2 + 1 = (5/3)x    multiply both sides by 3

12x^2 + 3 = 5x      rearrange

12x^2 - 5x + 3 = 0

This doesn't have a real solution......????

17/16= 1 1/16

Why would you think that?

Maybe in 3rd grade the bottom was the same all the time.

 Now in 6th grade you are being given harder questions that require more steps.  

Maybe that makes them look completely different.

 But they are really not different.

9 cubik liter

12 are right-handed

Of these....2 dislike jazz

So.....10 must like jazz

And since 15 total like jazz....5 of those must be left-handed

100 pi  equals  a little more than 314.......so....there's 314 of them......
