  • 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.
