Answer:

16/45

Step-by-step explanation:

Step 1:  When dividing fractions, use “KFC”.  It means Keep the first fraction, Flip the second one, and  

              Change it to multiplication

-4/20 ÷ -9/16    →    -4/20 ∙ 16/-9

Step 2:  Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end.  It’s easier arithmetic to reduce at this step.  The first fraction reduces because both the numerator and denominator are divisible by 4.  

-1/5  ∙   16/-9    

Step 3:  Multiply numerators and denominators together to get one fraction

(-16)/(-45)  

Step 4:  Cancel out the negatives, a negative divided by a negative is a positive.  Our final answer is

 

16/45

Given m||n, find the value of x.<br> +<br> (6x+10)<br> (10x+10)°
ludmilkaskok [199]

Answer:

(6x+10)°=(6x+10)°[vertically opposite angle]

now,

6x+10+10x+10=180°[being cointerior angle]

16x=180-20

x=160%16

x=10°

8/x2+6x times 2x product
sergejj [24]

Answer:

4 • (3x4 + 2)

 ———————

      x2    

Step-by-step explanation:

Step  1  :

            8

Simplify   ——

           x2

Equation at the end of step  1  :

  8    

 —— +  12x2

 x2    

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  x2  as the denominator :

           12x2     12x2 • x2

   12x2 =  ————  =  —————————

            1          x2    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

8 + 12x2 • x2     12x4 + 8

—————————————  =  ————————

     x2              x2  

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  12x4 + 8  =   4 • (3x4 + 2)

Polynomial Roots Calculator :

3.2    Find roots (zeroes) of :       F(x) = 3x4 + 2

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  3  and the Trailing Constant is  2.

The factor(s) are:

of the Leading Coefficient :  1,3

of the Trailing Constant :  1 ,2

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        5.00    

     -1       3        -0.33        2.04    

     -2       1        -2.00        50.00    

     -2       3        -0.67        2.59    

     1       1        1.00        5.00    

     1       3        0.33        2.04    

     2       1        2.00        50.00    

     2       3        0.67        2.59    

Polynomial Roots Calculator found no rational roots

Final result :

 4 • (3x4 + 2)

 —————————————

      x2
