2tan(x) + 2√3 = 3√3

2tan(x) = √3

tan(x) = √3 / 2

x = atan(√3 / 2)

x ≈ 0.71372437894476563082

8.337238494

There are a lot of rules for integration! Plus a lot of techniques!

Here is the power rule as a simple example.

int[Xn dx]

= (Xn + 1)/(n + 1) + C

( n does not equal - 1 )

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared", etc. All that I can see is three disjoint terms.

x^2 + 3x + 3 = 7

x^2 + 3x - 4 = 0

(x - 1)(x + 4) = 0

x = 1 or x = -4

- 9 = 5/17X

divide - 9 by 5/17, and this is the same as multiplying - 9 * 17/5

- 153/5 = X

------------------check in original equation

- 9 = 5/17(- 153/5)

- 9 = - 765/85

- 9 = - 9

------------------because - 765/85 = - 9

7x+8=2

.....-8..-8

7x=-6

7x/7=6/7

x=6/7

In conclusion, 7(6/7)+8=2

I'm sure you meant: x = - (6/7) or -6/7 (not 6/7).

slope = -1

y/5 = y/6+9

Multiply all terms by 30 to eliminate the fractions

6y = 5y+ 270

Subtract 5y from both sides

6y-5y = 270

y = 270

It is an expression.

two plus three equals five

x4 - 2x2 - 1 Complete the square, in order to write the difference of the two squares:

= x4 - 2x2 + 1 - 1 - 1

= (x2 - 1)2 - (√2)2

= [(x2 - 1) - √2][(x2 - 1) + √2]

= [x2 - (1 + √2)][(x2 - (1- √2 )] since 1- √2 < 0, write it as - (√2 -1) = (√2 -1)i2

= {x2 - [√(1 + √2)]2}{x2 - [(√(√2 - 1))i]2}

= [x - √(1 + √2)][x + √(1 + √2)]{x - [√(√2 - 1)]i}{x + [√(√2 - 1)]i}

Anytime you multiply a number by zero, the product will always be zero. Thus, whenever a number, regardless of its value, is multiplied by zero, there is only one possible solution: zero.

You can't convert square feet to ground since these terms are not totally related to each other. "square feet" measures the area of the object while "ground" is surface of the Earth.

Although this is not an Algebra question, here is my suggestion:

x + 3 + 2x = x + 3 subtract x + 3 to both sides

2x = 0 divide by 2 to both sides

x = 0

Derivative of e2x - y = 2e2x - dy/dx

Because: tan(60) = square root of 3

It ought to be possible, since the areas are the same. Try a L shaped cut.

* 1000 * 104 * 1.00X104

* One Thousand

The greatest common factor (GCF) for twenty-one and seventy-two is three.

(6 + y)/ 5= 21

Multiply both sides by 5: 6 + y = 105

Subtract 6 from both sides: y = 99

Yes

what in 1st order??

if you are asking about 1st order chemical equation then there will be only one variable with power 1.
