I believe you're asking about the one-sided limit,

Recall the definition of absolute value:
•
if 
•
if 
Since we're approaching -4 from the left, we're effectively focusing on a domain of
or
. So, by the definition above, we have
. Then in the limit, we have

Answer:

Step-by-step explanation:
<em>Hey there!</em>
3x * x = 3x^2
3x * 2x = 6x^3
So 3x is a factor of 3x^2 - 6x^3.
<em>Hope this helps :)</em>
5/6+1/12
=taking LCM we get 10+1/12
=11/12 is the answer..!!
QS would be 42. So the way i did it was I:
8x-51=3x-6
x=9
Plugged into both equations of QR and RS to then get the answer of 42
