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.
