Calculus

First, you have to solve 3x-1=11 for x.

You can start by adding 1 to both sides of the equation. That gets rid of the -1, and changes the equation to 3x=12. Then you divide both sides by three to cancel out the three, and your equation becomes x=4.

Finally with knowing x=4, you just need to add 2 to get 6.

x = - 4 and y = 0

5

x(x + 23)

4x2 = -12x, divide both sides by 4x: x = -3

(3x+1)(2x+2)

5

7+8+9=24

7x8x9=504

n = (x + 1)2 - 4

If it is x +49

The answer is x+49.It cannot be simplified further.

It it is x+4 9.I think it is 4 x 9=36,so the answers will be

x+4 9=x+4 x 9

=x+36

Be more specific when you ask a question.If you have any doubght

To be called an "equation", it must have an equal sign.

x and a half (1.5x)

12x+15p-6p+11x = 12x+11x+15p-6p = (12+11)x+(15-6)p = 23x + 9p

You might be confusing the GCF with the prime factorization. You need at least two numbers to find a GCF. 3 x 3 x 3 x 5 = 135 is the prime factorization.

100 X looks larger.

X=5

y - 4 = 2x +1

y = 2x + 5

The two intercept points are (0, 5) and (-5/2, 0)

7x/3 = 105

7x = 315

x = 45

4x - 1 = 7

Add 1 to both sides: 4x = 8

Divide both sides by 4: x = 2

Without that other number, all you've got is zero.

Solution 1:

3/4x + 2 = 12

x = [(12 - 2) * 4] / 3

x = 40/3 or 13.33

Solution 2:

0.75x + 2 = 12

x = (12 - 2) / 0.75

x = 13.33

25x-x**3 --> divide both numbers by x

x(25-x**2)
