Respuesta :

There should be 3 terms because X is a term, Y is a term, Z is a term, and Integers (such as -5 or 5) are terms.
 

Answer:

The number of like terms in the given expression are:

                                           3

                ( 14x , -x and 2x)

Step-by-step explanation:

Like terms--

The like terms are the terms which have the same variables with the same power.The coefficients of such terms may vary.

The expression is given by:

        14x-14y+7-x+z+2x

There are total 6 terms in given expression.

The number of terms with variable x are: 3  i.e.   14x , -x and 2x

The number of terms with the variable y is: 1 i.e. -14y

The number of terms with variable z is: 1 i.e.  z

and the number of constant term is: 1 i.e. 7

Hence, the number of like terms are: 3
