Answer:

k = -14

Step-by-step explanation:

We should cross-multiply

9/(k - 7) = 6 / k

9*k = 6 * (k - 7)

9k = 6k - 42

9k - 6k = -42

3k = -42

k = -14

Mrrafil [7]

Answer:

Tamar

Step-by-step explanation:

Vika [28.1K]

Answer:

$\fbox{8x+36}$

Step-by-step explanation:

1. Use the distributive property to write the problem without parentheses. The distributive property says that you can multiply a number next to parentheses by all the numbers inside parentheses. The picture below explains.

$4(2x+9)=\\\\(4*2x)+(4*9)=\\\\4(2x+9)= 8x+36$

Therefore, your answer is

$\fbox{8x+36}$
