Rationalizing the denominator of the expression, it is found that the simplified expression is given by:

[tex]\frac{\sqrt{6}(12x + 20x^2) + 3\sqrt{x} + 5\sqrt{x^3}}{x(96x - x)}[/tex]

It is given by:

[tex]\frac{3 + 5\sqrt{x^2}}{4\sqrt{6x^2} - \sqrt{x}}[/tex]

We rationalize the denominator, using the subtraction of perfect squares, hence:

[tex]\frac{3 + 5\sqrt{x^2}}{4\sqrt{6x^2} - \sqrt{x}} \times \frac{4\sqrt{6x^2} + \sqrt{x}}{4\sqrt{6x^2} + \sqrt{x}}[/tex]

Then, solving the expression:

[tex]\frac{(3 + 5\sqrt{x^2})(4\sqrt{6x^2} + \sqrt{x})}{16(6x^2) - x}[/tex]

[tex]\frac{12\sqrt{6x^2} + 3\sqrt{x} + 20x^2\sqrt{6} + 5\sqrt{x^3}}{96x^2 - x}[/tex]

[tex]\frac{\sqrt{6}(12x + 20x^2) + 3\sqrt{x} + 5\sqrt{x^3}}{x(96x - x)}[/tex]

The correct answers are 1008 hours are 6 weeks and 5 weeks are 840 hours.

The ratio indicates how many times one number is to the other number.For example, if you have 4 chocolates and 2 cakes the ratio of the chocolates and the cake will be 2:1 which means that chocolate is 2 times then the cake.

It is given that 168 hours is equal to 1 week. we need to find 1008 hours has how many weeks and 5 weeks has how many hours.

1.) 1008 hours has how many weeks

168 hours = 1 week

1 hour  =  1 / 168 weeks

1008 hours  = 1008 / 168  =  6 weeks

So 1008 hours has 6 weeks

2.) 5 weeks has how many hours.

1 week = 168 hours

5 weeks = 5 x 168 hours

5 weeks = 840 hours

So 5 weeks will have 840 hours.

Therefore correct answers are 1008 hours are 6 weeks and 5 weeks are 840 hours.

The expression equivalent to the given expression is [tex]\frac{4}{x-9}[/tex]

This are expressions written as a ratio of two expressions. Given the rational expression

[tex]f(x) = \frac{4(x-2)}{(x-2)(x-9)}[/tex]

Since (x-2) is common in both numerator and denominator, they wil cancel out to have the function below;

[tex]f(x) = \frac{4(x-2)}{(x-2)(x-9)}=\frac{4}{x-9}[/tex]

Hence the expression equivalent to the given expression is [tex]\frac{4}{x-9}[/tex]

Answer:

Number one is not reasonable

Answer:

should be 5.05

Step-by-step explanation:

rounded to nearest hundredth

Answer:

5.02

Step-by-step explanation:

Formula for area= π x r^2

(π is 3.14)

Formula for diameter= 2 x r

So all you basically have to do is go backwords with the first equation

20/π=6.36

Now you have 6.36, though you need to go even further back because of the ^2

√6.36=2.51

Now we have the radius, so stick that into the diameter formula

2 x 2.51

5.02 is the diameter :)

Answer:

2(x - 5)(x + 1)

Step-by-step explanation:

2x² - 8x - 10 ← factor out 2 from each term

= 2(x² - 4x - 5) ← factor the quadratic

consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)

the factors are - 5 and + 1 , since

- 5 × 1 = - 5 and - 5 + 1 = - 4 , then

x² - 4x - 5 = (x - 5)(x + 1)

then

2x² - 8x - 10 = 2(x - 5)(x + 1) ← in factored form

[tex]1 + 15 = 8x - 4x[/tex]

[tex]16 = 4x[/tex]

[tex]x = 4[/tex]

Steps:

[tex]4x+1= 8x-15[/tex]  

=>subtract 4 on both sides with 8x

[tex]1=4x-15[/tex]

=>now do add 15 both sides

[tex]16=4x[/tex]

=>Now divide 4x both sides

[tex]\frac{16}{4} =\frac{4x}{4}[/tex]

Let's solve this problem step-by-step:

   [tex]7 * 9 = (7*10)-(7*x)[/tex]

We know (7*10) - (7*x) is equivalent to the 7*(10-x)

 ⇒ based on the Distributive Properties

                           [tex]a*(b+c) = ab + ac[/tex]  

          [tex]7*(10+(-x))=(7*10)+(7*(-x)=(7*10)-(7*x)[/tex]

 So:

   [tex]7*9=7(10-x)\\9=10-x\\x=10-9\\x= 1[/tex]

Thus delta (the little triangle in this problem) in this case is 1

well, we know that θ is in the III Quadrant, where the sine is negative and the cosine is negative as well, or if you wish, where "x" as well as "y" are both negative, now, the hypotenuse or radius of the circle is just a distance amount, so is never negative, so in the equation of cos(θ) = - (2/5), the negative must be the adjacent side, thus
