B. \(18x^3 + 19x^2 - 20x + 21\)
C. \(23x^2 + 24x - 25\)
D. \(4x + 4\)

Answer :

The expression that represents a linear expression is 4x+4.

What is Expression?

An expression is combination of variables, numbers and operators.

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

In the given expressions the option A, B and C having variables with power more than one.

So those are not linear expression.

4x + 4 is a linear expression.

Because the variable x as power one.

Hence, the expression that represents a linear expression is 4x+4.
