Bonjour,

Calculer les valeurs de c et D pour :

a. x = 5

C = 3 * (x + 2)

C = 3 * (5 + 2)

C = 3 * 7

C = 21

D= 2 + 5 * x

D = 2 + 5 * 5

D = 2 + 25

D = 27

b. x = 1,5

C = 3 * (x + 2)

C = 3 * (1,5 + 2)

C = 3 * 3,5

C = 10,5

D= 2 + 5 * x

D = 2 + 5 * 1,5

D = 2 + 7,5

D = 9,5

C. X= 8

C = 3 * (x + 2)

C = 3 * (8 + 2)

C = 3 * 10

C = 30

D= 2 + 5 * x

D = 2 + 5 * 8

D = 2 + 40

D = 42

d.x=0

C = 3 * (x + 2)

C = 3 * (0 + 2)

C = 3 * 2

C = 6

D= 2 + 5 * x

D = 2 + 5 * 0

D = 2.
