Answer from: poreally6456

Option (c) is correct.

The values that are excluded for the given expression \frac{x-7}{x+9}  is -9 .      

Step-by-step explanation:

Given: Expression \frac{x-7}{x+9}

We have to find the values that are excluded for the given expression \frac{x-7}{x+9}                

For rational numbers , we exclude those values for which the denominator of the rational expression is 0.

Consider the given expression  \frac{x-7}{x+9}

Denominator of the given expression is x + 9

Put x+ 9 = 0

We have x = - 9

Thus, The values that are excluded for the given expression \frac{x-7}{x+9}  is -9 .

1. Subtract x+7. x = 2

2. Subtract x+7. x = 8

3. Subtract x+3. x = 4

4. Subtract x+1, divide by 2. x = 9

5. Subtract x+1. x = 8

6. Subtract 2x+2. x = 3

7. Subtract x+3, divide by 3. x = 6

(C) x=12

Step-by-step explanation:

Given: It is given that OP is parallel to NQ and ON=7, NM=21. PQ=x, QM=36.

To find: The value of x.

Solution: It is given that OP is parallel to NQ and ON=7, NM=21. PQ=x, QM=36, thus using the proportionality theorem, we get

\frac{ON}{OM}=\frac{PQ}{PM}

Substituting the given values, we have

\frac{7}{7+21}=\frac{x}{x+36}

Upon solving the above equation, we get

\frac{7}{28}=\frac{x}{x+36}

\frac{1}{4}=\frac{x}{x+36}

x+36=4x

x=12

Hence, the value of x is 12 and option C is correct.

Answer from: elite65

7 x 9 x 11 x 13  +  13  is a composite number because the answer is a positive number which is 9022.

7 x 9 x 11 x 13  +  13  is a positive integer that can be formed by multiplying small positive numbers which are 7, 9, 11 and 13. Equivalently, 9022 is a positive integer that has at least one divisor other than 1 and itself. For example, 9022 can be divided by 2. 9022 is exactly a number but it is not a prime number.

I hope you will understand my explanation!

My answer -

      This is essay about the time I ran away from home when I was six years old. This was a really important time in my life that taught me about living in the world all by your self. One night at my house I was laying down under the covers. And my mother and father were fighting my father was an abusive alcoholic.

      After every time my father and mother fought she had a another bruise on here face. I couldn't take it anymore I was tired of my mother an father fighting. So I decided to run away I packed my care bear suit case with clothes , food , and my favorite dolly. I climbed out the window of my room.

     They did not even notice I was gone so then I started walking. I met a nice man. Who had a kind face he asked me where were my parents. I did not speak I just stood there life less. He took out his phone and made a call. Then a police car showed up and two officers came out. They said they were coming to take me home.

      I got in the car just like they told me once we got to there were my parents standing there waiting for me. My mother and father gave me a hug and brought me inside. My mother asked me my why I ran away I said because I did not want them to fight anymore.

     She told my that you can't stop people from having conflict or disagreements. That is just life people have several disagreements all the time everyday. But you have got to learn how to end a disagreement . My mother gave me some really important information that day and I will always remember it.

P.S

Happy to help you have an AWESOME!!! day :)
