Factorize (3x2-48)/(x-4)

3(x+4)

Step-by-step explanation:

(3x2-48)/(x-4)

Factor out the common term 3.

3(x^2−16)/x-4

Rewrite

x^2−16 in the form, where a=x and b=4.

3(x^2−4^2)/x-4

Use Difference of Squares: a^2−b^2=(a+b)(a−b).

3(x+4)(x−4)/x-4

Cancel x−4.

3(x+4)

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

55

step-by-step explanation:

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
