It is not factorable. Factors of 21 are. 21 and 1
7 and 3. None of those add up to 12
Answer:
4
Step-by-step explanation:
-2x- 4 + 5x = 8
Collect like terms
-2x + 5x = 8 +4( when a variable crosses over equality sign it becomes either negative or positive depending on the sign)
3x = 12
Divide via by coefficient of x
X = 12/3
= 4
It would be around 138 minutes which is 2 hrs and 18 min so it would be C).
