(a) x,y,1
(b) x,y
(c) x, 1
(d) y, 1​

Answer 1

Answer:

The answer is option b ok.

Step-by-step explanation:

Terms: x,y,1

Answer 2

In the given expression the terms which are not constant are (b) x, y

Here the given expression is x + y + 1

In this expression 1 is constant as the values of 1 will remain fixed and will not change.

Meanwhile, x and y here are not constant they are variables. We can put different values in place of x and y and therefore they are not constant.

A variable is usually represented by any symbol or alphabet while constants have a fixed numerical value.

Therefore (option b) x, y will be the right answer to this question.
