Answer: c
Step-by-step explanation:
If the population triples every three hours, you would multiply three by the number of one hour to the power of three, making three hours. This function would triple it every three hours.
 
        
             
        
        
        
AAS and SAA don't prove congruence.  
You can have two triangles that have AAS or SAA and are not congruent.
From this picture, these triangles are congruent by ASA .
        
             
        
        
        
Given:
The expression is:

To find:
Part A: The expression using parentheses so that the expression equals 23.
Part B: The expression using parentheses so that the expression equals 3.
Solution:
Part A:
In option A,

 [Using BODMAS]
                       [Using BODMAS]

In option B,

 [Using BODMAS]
                      [Using BODMAS]

In option C,


In option D,

 [Using BODMAS]
                     [Using BODMAS]

After the calculation, we have  and
 and  .
.
Therefore, the correct options are B and D.
Part B: From part A, it is clear that

Therefore, the correct option is C.
 
        
             
        
        
        
Answer:
x=11°
Step-by-step explanation:
-Sum of angles of a triangle should alway be 180 degrees 
35+110+2+3x=180
-Add all known values
147+3x=180
-Subtract 147 from both sides
3x=33
-Isolate x by divind both sides by 3
x=11°
 
        
             
        
        
        
I think the answer is -48°F
