Consider this expression.

9/4x2 - 12x + 7x/x^2 - 9

The least common denominator of the two rational terms is ( )( )( )

The answer is in the image attached. I hope it is helpful.

The **least common denominator **of two given rational expression are ** 4x**, **(x-3) **and** (x+3)**.

The factored denominator of two rational terms are called least common denominator of two rational numbers.

How to find the least common denominator of two rational terms?To find the least common denominator of two rational terms, we factor the expression and multiply all the distinct factors.

According to the given question

We have two rational expressions

[tex]\frac{9}{4x^{2} -12x}[/tex] and [tex]\frac{7x}{x^{2} -9}[/tex]

Now let's factorize the denominators

[tex]4x^{2} -12x =4x(x-3)[/tex]

and, [tex]x^{2} -9=(x+3)(x-3)[/tex]

Therefore,

[tex]\frac{9}{4x^{2} -12x}+\frac{7x}{x^{2} -9}[/tex]

⇒[tex]\frac{9}{4x(x-3)} +\frac{7x}{(x-3)(x+3)}[/tex]

⇒[tex]\frac{9(x+3)+7x(4x)}{4x(x-3)(x+3)}[/tex]

Therefore, the **least common denominator **of two given rational expression are ** 4x**, **(x-3) **and** (x+3)**.

With a headwind a plane traveled 128 km in 2h. The return trip with a tail wind took 24 min less. Find the air speed of the plane.

WILL GIVE BRAINLY TO FIRST ANSWER

Based on the information given, it can be noted that the **air speed **that the **plane **has will be **71.1 km per hour.**

The number of **hours** used for the return trip will be:

= 2 hours - 24 minutes.

= 1 hour 36 minutes.

**= 1.6 hours.**

Therefore, the **speed **of the air plane will be:

**= (128 + 128) / (2 + 1.6)**

= 256/3.6.

**= 71.1 km per hour.**

I am asking how this is when I found the median is 14!

Hi there!

2 3 5 5 9 11 13 14 14 17 20 22 24 28

If we count up the numbers, we find that there are 14 numbers. This means that we must take the average of the middle two numbers to find a median since the amount of numbers is not odd.

Count 6 from both sides and we get the middle two numbers to be:

13 14

Take the average:

**(13 + 14)/2 = 13.5 **

**This must be done if the amount of numbers given is EVEN.**

**Answer:**

**Step-by-step explanation:**

There are an even number of entries that make up the Data Set. (14 entries)

When you have an even number, you take the two entries that are at the center to find the median.

The values at the middle are entry seven which is 13 and entry eight, which is 14.

Now average these two. You get (13 + 14)/2 = 27 / 2 = 13.5

Otherwise I think you are correct.

A sample of n = 5 scores has M = 20 and s2 = 4. What is the sample standard deviation?

O 20

O 5

02

O 16

5 I think sorry if I’m wrong

The sample standard **deviation **is 2. Therefore, the correct answer is option C.

Given that, a sample of n=5 scores has M=20 and s²=4.

The **standard deviation **is the fundamental measure of data point dispersion from the mean of a given data set. If the data points on a given distribution are more spread out, the standard deviation will be greater. In contrast, if the data points are close together, the standard deviation will be low.

The standard deviation is simply the square root of the **variance**;

Here, [tex]s=\sqrt{4}[/tex]

[tex]s=2[/tex]

Therefore, the correct answer is option C.

6) A geologist collects rocks. He has three types, sedimentary, metamorphic and

igneous. The ratio of sedimentary rocks to metamorphic rocks is 2:3.

The ratio of metamorphic to igneous is 9:10.

What is the ratio of sedimentary to igneous?

**Answer:**

3:5

**Step-by-step explanation:**

s:m = 2:3

m:i = 9:10

convert m to same number so they are comparable

s:m = 6:9 (multiple so the ratio is still the same as 2:3)

m:i = 9:10 (the same thing as before)

s:i = 6:10

s:i = 3:5 (simplify)

**Answer:**

unit rate 1:8

**Step-by-step explanation:**

A rock is thrown into a pool 72 inches deep. The rock sinks at a rate of 4 inches per

second (s). The rock's height (h) above the bottom of the pool is given by the

equation: h = 72 – 4s. After how many seconds will the rock be half way to the

bottom?

Half of 72 is 36. If you divided 36 by 4, you would get 9. So, s = 9 and means that it takes 9 seconds for the rock to be sunk half way.

Which of the following is equivalent to:

−−(2+5)−(3−7)?

**Answer:**

You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!

Bethany is working her way through school. She works two part-time jobs for a total of 23 hours a week. Job A pays $5.70 per hour, and Job B pays $7.10 per hour. How many hours did she work at each job the week that she made $143.70.

**Step-by-step explanation:**

x = number of hours A

y = number of hours B

x + y = 23

5.7x + 7.1y = 143.7

from the first equation we get

x = 23 - y

and that we use in the second equation

5.7×(23 - y) + 7.1y = 143.7

131.1 - 5.7y + 7.1y = 143.7

1.4y = 12.6

y = 12.6/1.4 = 9

x = 23 - y = 23 - 9 = 14

she was working 14 hours on job A and 9 hours on job B.

Write the equation of the line graphed below in slope-intercept form.

**Answer:**

y=1/2x+3

**Step-by-step explanation:**

grabbing two points in this case (0,3) and (2,4)

we use the rise over run formula meaning it rises 1 and runs 2 so our slope is 1/2

to get the y intercept just look at where the line touches the y line in this case at 3

using the equation y=mx+b and m is slope and b is y interecpt we plug in the numbers

so we get y=1/2x+3
