Step-by-step explanation:
 A = (1/2)bh ---> h = 2A/b = 2(12 cm^2)/(5 cm) = 4.80 cm
---> x^2 = h^2 + (b/2)^2
 = (4.8 cm)^2 + (2.5)^2
 = 23.04 cm^2 + 6.25 cm^2
or x = 5.41 cm
Therefore, the perimeter P is
P = 2x + b = 2(5.41 cm) + 5 cm = 15.8 cm
 
        
             
        
        
        
Two parallel lines never intersect, therefore they will never have a solution. 
One line could be x=6 and the other could be x=2
Hope this helps :)
        
             
        
        
        
Answer: 
Step-by-step explanation:
Here the total numbers are 1,  4,  3,  7,  6
Since the total number of possible arrangement =  
 
The total number of the odd numbers in the given numbers = 3
Thus the possible arrangement that the first three digits will be odd numbers = 
Thus, the probability that the first three digits of Irvings ID number will be odd numbers = the possible arrangement that the first three digits will be odd numbers / total possible arrangement =   
 
= 
 
        
             
        
        
        
Answer: It would be D
Step-by-step explanation:
4-7 equals -3
-1-4 equals -5
Cancel out the negatives which makes a positive
 
        
                    
             
        
        
        
You may find it easiest if you convert all the fractions to decimal form:
5.433...
5.166...
5.756
Now reorder these from smallest to largest.
Note:  I had to guess that by "68,90," you actually meant "68/90."
