                       ANSWER
                           3
                   1.  i) 4x is a monomial expression as it contains only one term.
                           2
                       (ii) x  - 1 is a binomial expression because it contains two terms.
                                2
                            2
                       (iii) x  - y  is a binomial expression as it consists of two terms.
                                   2
                             2
                       (iv) 3x  + 4y  +5z contains three terms. So, it is a trinomial.
                                3
                           3
                       (v) a  + b  - 3ab + 5 contains four terms. So, it is a quadrinomial.
                                          2
                                      2
                            2
                                 2
                       (vi) a  + b  + c  - d is a quadrinomial, because it contains four terms.
