Properties of a bar graph: 
1). There should be equal space between the bars or the columns.
2). Width of each bar or columns should be same.
3). All bars should have same base.
4). Height of each bar will show the value of the data.
By these properties,
- Space between London-Paris, Rome-Oslo are not equal.
- Width of Munich bar is different from other bars.

Answer:
b and d
Step-by-step explanation:
3 + root 2 = 4.414...
30/root 19 = 6.882....
5.1 - (15/root 24) = 2.038....
4pi = 12.5663....
b and d
 
        
             
        
        
        
It simplifies down to x + 4
