    Step-by-step explanation:

    Given expression is

    2 (a+1) + 4b+3

    Simplify to get

    =2a+4b+5

    So we find that 2 is a coefficient of a and 4 the coefficient of b and 5 the constant term

    a) The "4" in the second term is a coeffiicient. - - True because b has coefficient 4

    b) The "a" in the first term is a factor.--Not true because 2a only has a as factor and not the full expression

    c) (a+1) is a factor is true as I term has 2 and a+1 as factors

    d) 1 is a coefficient - - Not true because coefficient here is 2

    e) The "b" is not an exponent of II term but a factor

    f) The "3" is a constant is true.
