The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.
Step-by-step explanation:
The given is,
              a = 5
              b = x - 1
              c = x
Step:1
       Pythagorean theorem is,
                 ................................(1)
................................(1)
       (  It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides )
       From the given values the equation (1) becomes,
                        
                              (  )
 )
                25 + (  + 1 - 2x ) =
 + 1 - 2x ) = 
                            25 + 1 -2x = 0               ( ∵ Eliminate  in both sides)
 in both sides)
                                      26 = 2x
                                        x = 13
Step:2
         From the values of x,
                     a = 5
                     b = ( 13 - 1 ) = 12
                     c = 13
Result:
             The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.
 
        
             
        
        
        
Remember that an exponent means repeated multiplication.
The exponent of 4 means you have four  's mutiplied together:
's mutiplied together:
       
And then each exponent of 2 inside means you have two  's multiplied inside each set of parentheses.:
's multiplied inside each set of parentheses.:  
     
There are 8 b's there when you expand this out.
 
        
             
        
        
        
Lengthof train=X
platform length=180
total distance=x+180
speed=60km/hr=60×5/18=(300/18)m/
Time =18s
Time =Distance/speed
18=X+180/(300/18
18×300=18(X+180)
300=X+180
x=300-180=120
so length of the train=120m
        
             
        
        
        
Pi•r^2
Radius= 15
Plug in and that should give you the blue area. =706.858
If you added 3 feet to the circle that would change the radius to 18 so back to the formula...
Pi•18^2
=1,017.876
To find the shades you would have to subtract the two and get your answer 
Interesting. Either the answer choices are wrong or I am.... is the formula right? Lol it’s been too long
        
                    
             
        
        
        
Answer:
country = 0.31
rock and roll =0.47
Blues = 0.22
Step-by-step explanation: 
country = 11
Rock and roll= 17
blues = 8
Total = 36
the probabilities by dividing the frequencies by the total. ( round to the nearest hundredth.)
11/36 = country
17/36 = rock and roll
8/36 = blues
Divide 
country = 0.31
rock and roll =0.47
Blues = 0.22
