Respuesta :

the answer is A because the

1.  x + 2xyz

2.  3x + y + z

3.  2x2y + x2 − 3x + 4

4.  9x2yz

it goes 3, 2, 1, 4

The expressions from greatest to least by number of terms  is

III > II > I > IV .

What are terms?

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

According to the question

Arrange expressions from greatest to least by number of terms :

Calculating number of terms in each expression:

I. x + 2xyz

This expression is having 2 terms .

II. 3x + y + z

This expression is having 3 terms .

III. 2x²y + x² − 3x + 4

This expression is having 4 terms .

IV. 9x²yz

This expression is having 1 terms .

Now arranging them in greatest to least by number of terms :

III > II > I > IV

Hence, The expressions from greatest to least by number of terms  is

III > II > I > IV .
