Yes. Everything please.

$$2+2 = 4$$

X is a variable in math, and is commonly used, like n.

if you see letters in math, they are variables.

Variables are unknown numbers, and I will give an example.

34+x=51

So, to find the answer, just subtract 34 from 51. And you get 17.

So, x=17

Do you want what I have so far?

$$\sqrt7=2.6457513110645906$$

bruh really, go read this website:http://www.mathsisfun.com/converting-decimals-fractions.ht

Yeah! They are so good!

Ok. Can you take a photo of the essay? The whole essay please? This can help me answer the question.

We need the tangent here

tan(65°) = opp/200        multiply both sides by 200

200tan (65°) = opp = ht of tower = about 429m

11 + 3x = 8 - 2x     add 2x to both sides and subtract 11 from both sides

5x = -3                   divide by 5 on both sides

x = -3/5

hahaahahahahahahahahahahahahahaha

This equals 8^9,

so $${{\mathtt{8}}}^{{\mathtt{9}}} = {\mathtt{134\,217\,728}}$$

If we have log(2x+1)=log(4x). we can just set 2x + 1  =  4x and solve

So we have

2x + 1 = 4x

1 = 2x

 x = 1/2

------------------------------------------------------------------------------------------------

If we have log(2x)+1=log(4x)  .....we have (writing "1" as "log 10" )

log(2x)+ log 10 = log4x    and by a property of logs, we can write

log(2x*10) = log(4x)

log (20x) = log(4x)

And setting 20x = 4x   →    x = 0     ......but this answer isn't possible because we would be taking the log of 0 and that's undefined......so..... log(2x)+1=log(4x) has no solution....

Really??

This page will convert 60 GB to MB....then just divide the conversion by 7 to get your answer........

(x-2) (x+3) = (x+1) (x-3)  simplifying on both sides, we have

x² + x - 6  = x² -2x - 3      subtract x² from both sides

x - 6 = -2x - 3     add 2x, 6 to both sides

3x = 3                 divide by 3 on both sides

x = 1

Make sure to check this answer in the original problem !!!!

1/(7+4*sqrt(3))+ 1/(7-4*sqrt(3))   getting a common denominator, we have

[(7 - 4√3)  + (7 + 4√3)] / [ 49  - 16(3)] = 

14 / (49 - 48) =

14 / 1

Answer is 14.

you can aply (a+b)(a-b)=a^2-b^2 this formula on this math problem.

m=120/60-150/20

Well...we either have

2 - 7.5 =  -5.5     or, you might have meant this.......

(160 - 150) / (60 - 20)  =

10/40  = 1/4

√104+√40+√160=x√x    write the right side in exponential form

2√26 + 2√10 + 4√10 = x^3/2       combine like terms

2√26 + 6√10 = x^3/2       exponentiate both sides to the 2/3rds  power

[(2√26 + 6√10)²]³ =  x  =  about 9.476

Thanks Rosala and anonymous,   

You should edit your answer to make it correct.  BUT make sure write "edited" in there too.:) 

√8 +√(18 + 2) =

√8 + √20  =

√4 * √2  + √4 * √5 =

2√2 + 2√5 =

2(√2 + √5)

Note that the first "rule" of factoring is to take out any common factors, first. Once we have done this, if we have a difference of two squares remaining, we just write the square root of both factors twice........separate the first pair with a "+" and the second pair with a "-"

So, the frist one has no common factors.......take the square root of both terms, wtite them twice, and separate them with a "+" and a "-".....so we have

(3x + 5y )   ( 3x - 5y )   ...... and that's the factorization

For the second one, take out the common factor of 4 and we have...

4(9x² - 1).......now, just factor the inside expression like the first one....don't forget to append the "4" to it when you're finished !!!

The third one is similar to the second one

For the last one, take out the common factor of "2"  and we're left with

2(x^4 + 7x^2  + 12)......this isn't a perfect square trinomial, but can be factored as

2(x^2 + 4) (x^2 + 3)

Hope that helps

A constant function doesn't have an inverse. To see why, note that if we have a function such as y = a, then it isn't one-to-one, because an infinite number of x values produce the same y value (namely, "a"). And  x = a can never have an inverse, because this is a vertical line - which doesn't meet the criteria of a "function." (It fails the vertical line test at x = a.)

That's my take on this one........
