Need in this 2 math questions 20. q varies inversely as the square of p, and q = 36 when p = 7. find q when p = 6. a. q = 6 b. q = 42 c. q = 176 d. q = 49 12. complete the property of exponents. (ab)n = a. an + bn b. anbn c. abn d. an – bn

20. OPTION D.

12. OPTION B.

Step-by-step explanation:

20. An inverse variaton equation has this form:

Where "k" is the constant of variation.

If  Q varies inversely as the square of p, then the equation is:

Knowing that when , you can solve for "k" and caculate its value:

Then, to find the value of "Q" when , substitute the known  values into  :

12. Given , you get:

Then:

This matches with the option B.
