solve the inequality; x2-x-2>0

Answers

Answer 1

Answer:

x > 2/3

Step-by-step explanation:

2x -x - 2 > 0  

add 2x and x (It becomes 3x)

3x -2 >0

subtract 0 from both sides

3x> 2

divide 3 on both sides

And the answer is

X> 2/3

Step-by-step explanation:

"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.

C = 2· π· r

What is the radius of the wheel ​?

321 = 2· π· r, divide both sides of the equation by 2 π

what is the distance formula?

Answers

Answer:

Distance formula. The formula for distance, if you know time (duration) and the average speed, is: d = v x t. where v is the velocity (average speed), t is the time and d is distance, so you can read it as Distance = Speed x Time. The result will depend on the unit of the speed metric, for example if speed is given in mph,

Step-by-step explanation:

A (m 1 ,n 1) and B (m 2 ,n 2) are the coordinates of the two given points in the coordinate plane.

The distance between the two points can be calculated using the distance formula, d = √ (m2 - m1)2 + (n2 - n1)2

Finally, express the given solution in proper units.

help! which expression is equivalent to 14x + 35 - 21 y​

Answers

Answer:

7(2x + 5 - 3y)

Step-by-step explanation:

Looking at the Factors below the question, what do you notice?

I notice that 14, 35 and 21 all have a GCF of 7

With this, we can now start factoring, but before we start, keep in mind that we need to find terms that when multiplied with 7 give us 14x, 35, and -21y.

Be careful with the signs ( + and -) when factoring!

14x + 35 - 21y

7(2x + 5 - 3y)

Check you answer to make sure if results in our original expression:

7(2x + 5 - 3y) <== distribute seven

7(2x) + 7(5) + 7(-3y)

14x + 35 - 21y

Therefore, we have correctly factored the expression, and the correct answer is 7(2x + 5 - 3y)

Hope this helps!

Which is the completely factored form of 4x2 28x 49? (x 7)(4x 7) 4(x 7)(x 7) (2x 7)(2x 7) 2(x 7)(x 7)

Answers

The completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)

How to find the factors of a quadratic expression?

If the given quadratic expression is of the form ax^2 + bx + c, then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:

[tex]b = \alpha + \beta \\ ac =\alpha \times \beta[/tex]

Then writing b in terms of alpha and beta would help us getting common factors out.

Sometimes, it is not possible to find factors easily, so using the quadratic equation formula can help out without any  trial and error.

For this case, the given quadratic expression is:

[tex]4x^2 + 28x + 49[/tex]

So we've to find two numbers such that:

Their sum = b =  28

Their product = [tex]ac = 4\times 49 = 196[/tex]

We can see that 196 is square of 14, and that 14 added twice forms 28, thus:

14 + 14 = 28

14×14 = 196

Writing b = 28 as sum of 14 twice, we get:

[tex]4x^2 + 28x + 49 = 4x^2 + 14x + 14x +49 \\4x^2 + 28x + 49 = 2x(2x+7) + 7(2x + 7)\\4x^2 + 28x + 49 = (2x+7)(2x+7)[/tex]

Thus, the completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)
