Which choice is equivalent to the product below for acceptable values of X?

C is the answer

to solve this, you just have to multiply the values inside the square roo, and the 6x will be distributed to each values inside the other radical.

Note: You can multiply the radicals because they both have a square root.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
