bonjour pourriez vous m'aider à l'exercice 37 svp merci d'avance

1) Programme 1                                                 Programme 2
          + 5             x 2                                                x 2           + 10
a. 0 --------} 5 -----------} 10                                  0 --------} 0  ----------} 10
          + 5              x 2                                               x 2            + 10
b. 6 ---------}  11 -----------}  22                             6 --------} 12 ----------} 22
            + 5                x 2                                             x 2           + 10
c. 9,5 --------} 14,5  ---------} 29                           9,5 -------} 19 ----------} 29

 2) P1                                                                  P2
         + 5              x 2                                                x 2             + 10
    n --------} n +5 ---------}  2 (n + 5)                     n ---------} 2n ----------} 2n + 10
                                          
   N =  2 (n + 5)                                                   R = 2n + 10

3) N = 2 (n + 5)
       =  2 x n + 2 x 5
       = 2n +10
Leila a raison. N = R = 2n + 10

1.
a)
 P1= (0+5)×2
     = 10
P2= 0×2+10
    = 10

b)
P1= (6+5)×2
    = 22
P2= 6×2+10
    = 22

c)
P1= (9,5+5)×2
    = 29
P2= 9,5×2+10
    =29

2.
a)
P1=(n+5)×2
P2= 2n+10
c)
P1= (n+5)×2
    = n×2 + 10
    = P2
Donc oui elle a raison puisque les deux programmes sont égaux.
