Bonjour,

a) x = 3

E = 5 * x

E = 5 * 3

E = 15

F = 2 * (4 + 5 * x)

F = 2 * (4 + 5 * 3)

F = 2 * (4 + 15)

F = 2 * 19

F = 38

G = 2 + 3 * x

G = 2 + 3 * 3

G = 2 + 9

G = 11

b) x = 10

E = 5 * x

E = 5 * 10

E = 50

F = 2 * (4 + 5 * x)

F = 2 * (4 + 5 * 10)

F = 2 * (4 + 50)

F = 2 * 54

F = 108

G = 2 + 3 * x

G = 2 + 3 * 10

G = 2 + 30

G = 32

c) x = 0,1

E = 5 * x

E = 5 * 0,1

E = 0,5

F = 2 * (4 + 5 * x)

F = 2 * (4 + 5 * 0,1)

F = 2 * (4 + 0,5)

F = 2 * 4,5

F = 9

G = 2 + 3 * x

G = 2 + 3 * 0,1

G = 2 + 0,3

G = 2,3.
