-2(3x - 4) + 2x  =  6x(1 - x) - 6

Using the distributive property:

-6x + 8 + 2x  =  6x - 6x² - 6

Simplifying:

-4x + 8  =  6x - 6x² - 6

Getting all the terms to one side:

    0  =  - 6x² + 10x - 14

To make the problem easier to solve, divide every term by -2:

   0  =  3x² - 5x + 7

Use the quadratic formula with a = 3, b = -5, and c = 7:

   x  =  [ 5 ± √( (-5)² - 4(3)(7) ) ] / [ 2(3) ]

   x  =  [ 5 ± √( 25 - 84 ] / [ 6 ]

   x  =  [ 5 ± √( -59 ) ] / [ 6 ]

The formula to find a z-score:  z  =  (value - mean) / standard deviation

--->   z  =  (36.8 - 35) / 0.5  =  3.6

There are exterior angles of parallel lines, exterior angles of triangle, and exterior angles of polygons. Which ones are you referring to?

thanks that helped

The calculator at this site will answer this question. Just enter it into the calculator the same way you typed it here. The answer is huge!

For the lower number: find 15% of 119.7 and add it to 119.7:

--->   0.15 x 119.7  =  17.955   --->   119.7 + 17.955  =  137.655

For the upper number: find 20% of 119.7 and add it to 119.7:

--->   0.20 x 119.7  =  23.94   --->   119.7 + 23.94  =  143.64

The amount of tile should be between these two numbers.

2L + 2(1/3L)  =  224

2L + (2/3)L  =  224

Multiply each term by 3 (the lowest common denominator):

6L + 2L  =  672

8L  =  672

Divide both sides by 8:

L  =  84

I Dont Get The Question But If Your Talking About 4*4*4*4 It Equals 256

Yup its a disease 

A LOT of what?

V= (1/3)(3.14)(R)^2(H) Or (One Third) * Pi * (radius) squared * Height

Well, percent is per hundred, so we can say 10 percent as 10 per hundred, or 10/100, or even more, 1/10. The word "of" usually, if not always, indicates multiplication. So, 

$$\frac{1}{10} * 192.14 = 19.214$$

That's just basic math, there.

Here we go!

So, the easiest thing to do is to distribute the 2 and the 5, like so:

$$2(x+1)-5(x-3)=5 \Rightarrow 2x+2-5x+15=5$$

How'd I do this? Well, you distribute by multiplying the number outside (the 2) with each number INSIDE (the x and the 1). We also did this with the 5.

Now, let's simplify this equation.

$$2x+2-5x+15=5 \Rightarrow 2x-5x+2+15=5 \Rightarrow -3x+17=5$$

So, what I did here was put the terms with x next to each other, and those without next to each other. Then I added the like terms, which are next to each other. So, 2x-5x=-3x (Just add the coefficients, or the numbers in front of x.) and 2+15=17. Now the equation looks MUCH easier to solve. We want x all by itself, so we can subtract 17 on both sides.

$$-3x+17=5 \Rightarrow -3x+17-17=5-17 \Rightarrow -3x=-12$$

Now, that looks WAY easy. To get rid of x, we divide both sides by negative three, since division is the opposite of multiplication.

$$\frac{-3x}{-3} = \frac{-12}{-3} \Rightarrow x = 4$$

There we go! All done!

2(x+1)-5(x-3)=5 

2x+2-5x-15=5 do the problem now 

A LOT!! including me

It Equals -34

Well, there are 24 hours in a day. If you spend 3 out of those 24 hours playing the piano, we can write that as a fraction:

$$\frac{3}{24}$$

Well, we can simplify that. Let's ask ourselves two questions: What are the factors of 24? Is 3 a factor of 24?

Well, here's some factors of 24:

1*24

2*12

3*8

4*6

Which one has 3? Right, 3*8! So, let's rewrite this equation to:

$$\frac{3/3}{24/3}$$ which becomes $$\frac{1}{8}$$ when solved.

So, the answer is 1/8 of the day.
