Answer:
Option C 
Step-by-step explanation:
we have

The compound inequality can be divided into two inequality
 -----> inequality A
 -----> inequality A
 ----> inequality B
 ----> inequality B
Solve inequality A


Divide by -3 both sides
when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol 

Rewrite

The solution of the inequality A is the interval (-∞,-3]
Solve the inequality B


Divide by -3 both sides
when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol 

The solution of the inequality B is the interval [-6,∞)
The solution of the compound inequality is 
 [-6,∞) ∩ (-∞,-3]=(-6,-3]

 
        
             
        
        
        
B
For example if it has been 2 months (l=1.25 times 2) the length would be 1.5 cm
        
             
        
        
        
Answer: 5+3 times 4+2 is 48
Step-by-step explanation:
 
        
                    
             
        
        
        
You're almost finished.
(sin/cos) times cos = 0
Look at the left side.  You could write it as (sin x cos) / cos = 0
and simply divide numerator and denominator by the cosine (cancel it).
Then what do you have left ? . . .  <u>sin(x) = 0</u>       Do I need to finish this for you ?
