what is the greatest common factor (GCF) of the numerator and denominator of the rational expression below? (6x+18)/(x^2-x-12)

Answers

Answer:

GCF = x+3

Step-by-step explanation:

(6x+18)/(x^2-x-12) = 6 (x+3)/(x^2 +3x - 4x -12)

                            = 6(x+3)/( x(x+3) - 4(x+3) )

                            = 6(x+3)/( (x-4)(x+3) )

The greatest common factor (GCF) of the numerator and denominator of the rational expression [tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]  is (x + 3) .

What is  greatest common factor (GCF)?

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.  

According to the question

The rational expression :

[tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]

The greatest common factor (GCF)  of the numerator and denominator

Step 1 : We take out factors of numerator

(6x+18) = 6 (x + 3)

Step 2 : Then we take out  factors of denominator

[tex](x^2-x-12)[/tex] = x² - (4-3)x - 12

                    =  x² - 4x + 3x - 12

                    =  x (x - 4) + 3(x - 4)

                    = (x + 3) (x - 4)  

Now , The greatest common factor (GCF)  of the numerator and denominator is  (x + 3)  which is present in both .

Hence, the greatest common factor (GCF) of the numerator and denominator of the rational expression [tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]  is (x + 3) .

Tom is 77 inches tall and shrinking at a rate of 0.75% every eyar. How tall will he be after 15 years?


Whats the exponential function

Answers

Answer:

The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.

Step-by-step explanation:

Since Tom's initial height is 77 inches. After one year:

height(1) = 77*(1 - 0.0075) = 77*0.9925

After two years:

height(2) = height(1)*(0.9925) = 77*0.9925*(0.9925) = 77*(0.9925)²

After three years:

height(3) = height(2)*0.9925 = 77*(0.9925)²*0.9925 = 77*(0.9925)³

And so on, therefore the expression that represents his height is:

height(n) = 77*(0.9925)^n

Where n is the number of elapsed years. For 15 years we have:

height(15) = 77*(0.9925)^(15) = 68.7778 inches

The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.

This circle is circumscribed about quadrilateral ABCD. What is the value of x?

Answers

Answer:

The value of x is 56°

Step-by-step explanation:

Given that opposite angles in a cyclic quadrilateral is add up to 180°. So in order to find x, you have to write an expression in terms of x :

[tex]97 + x + 27 = 180[/tex]

[tex]x + 124 = 180[/tex]

Next you have to solve it by substracting 124 to both sides :

[tex]x + 124 - 124 = 180 - 124[/tex]

[tex]x = 56[/tex]

1 foot = 12 inches. 1 inch = 2.5 centimetres. Change 5 feet 10 inches to centimetres​

Answers

I guess the answer should be 177.8 cm.

The measurement of 5 feet 10 inches to centimeters​ is 175 centimeters.

What is Unit of Measurement?

Units of measurement are defines ad the definite magnitude of a physical quantity. It is used to find a number that shows the amount of something.

Here we have to convert the units of measurement feet and inches to centimeters.

We have,

1 foot = 12 inches and 1 inch = 2.5 centimeters

We have to change 5 feet 10 inches to centimeters​.

1 foot = 12 inches

⇒ 5 feet = 12 × 5 inches

              = 60 inches

So, 5 feet 10 inches = 60 inches + 10 inches

                                 = 70 inches

1 inch = 2.5 centimeters

70 inches = 70 × 2.5 centimeters

                 = 175 centimeters

Hence we got 5 feet 10 inches as 175 centimeters.
