Answer 2

THE EXPRESSION “x+3” IS IN ONE VARIABLE.

Explanation:

• When we write an algebraic expression, we use variables and constant.
• The variables are such symbols which can hold any value. They are generally represented by the help of alphabets.
• In the given expression “$x+3$” only one variable "x" is given and a constant "3" is given, though it is a binomial expression.
• The degree of polynomial is 1 so it is a linear equation in one variable. The degree is defined as the highest power of the variable.
• Therefore, the given expression “$x+3$” is in one variable.
