Answer:

B

Step-by-step explanation:

When you are trying to find if they are equivalent, you only want to use one value. If they are both positive, it doesn't mean that they are quivalent. They would have to be the same.

(x-x_{0})^{2} +(y-y_{0})^{2}=r^{2}
\\ \\(x+9)^{2} +(y+7)^{2} = 17^{2}
\\ \\(x+9)^{2} +(y+7)^{2} = 289

4g^2+9/h^2+7g^2+4/h^2+1​
SashulF [63]

Answer:

   11g2h2 + h2 + 13

 ———————————

                h2      

Step-by-step explanation:

Step  1  :

            4

Simplify   ——

           h2

Equation at the end of step  1  :

               9              4

 ((((4•(g2))+————)+(7•(g2)))+——)+1

             (h2)            h2

Step  2  :

Equation at the end of step  2  :

               9         4

 ((((4•(g2))+————)+7g2)+——)+1

             (h2)       h2

Step  3  :

            9

Simplify   ——

           h2

Equation at the end of step  3  :

              9        4

 ((((4•(g2))+——)+7g2)+——)+1

             h2       h2

Step  4  :

Equation at the end of step  4  :

             9              4    

 (((22g2 +  ——) +  7g2) +  ——) +  1

            h2             h2    

Step  5  :

Rewriting the whole as an Equivalent Fraction :

5.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  h2  as the denominator :

            22g2     22g2 • h2

    22g2 =  ————  =  —————————

             1          h2    

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 :

5.2       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:

22g2 • h2 + 9     4g2h2 + 9

—————————————  =  —————————

     h2              h2    

Equation at the end of step  5  :

   (4g2h2 + 9)             4    

 ((——————————— +  7g2) +  ——) +  1

       h2                 h2    

Step  6  :

Rewriting the whole as an Equivalent Fraction :

6.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  h2  as the denominator :

          7g2     7g2 • h2

   7g2 =  ———  =  ————————

           1         h2  

Adding fractions that have a common denominator :

6.2       Adding up the two equivalent fractions

(4g2h2+9) + 7g2 • h2      11g2h2 + 9

————————————————————  =  ——————————

         h2                  h2    

Equation at the end of step  6  :

  (11g2h2 + 9)     4    

 (———————————— +  ——) +  1

       h2         h2    

Step  7  :

Adding fractions which have a common denominator :

7.1       Adding fractions which have a common denominator

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

(11g2h2+9) + 4     11g2h2 + 13

——————————————  =  ———————————

      h2               h2    

Equation at the end of step  7  :

 (11g2h2 + 13)    

 ————————————— +  1

      h2          

Step  8  :

Rewriting the whole as an Equivalent Fraction :

8.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  h2  as the denominator :

        1     1 • h2

   1 =  —  =  ——————

        1       h2  

Adding fractions that have a common denominator :

8.2       Adding up the two equivalent fractions

(11g2h2+13) + h2     11g2h2 + h2 + 13

————————————————  =  ————————————————

       h2                   h2      

Trying to factor a multi variable polynomial :

8.3    Factoring    11g2h2 + h2 + 13

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Final result :

 11g2h2 + h2 + 13

 ————————————————

        h2
