Question

Match the following statements with their suitable labels.:

• A. Constant
• B. Variable
• C. Algebraic expression

Answer 1

An entity with a fixed value is called a constant.
Example: 2, -3, 0.8, etc.

An entity which varies or changes its value is called a variable.
Example: $x$, $y$, etc.

An algebraic expression is a combination of variables and constants connected with mathematical operators.
So, 4$x$ - 5 is an algebraic expression.
