Question: 1 / 400

What is the simplified form of the expression (2x + 3x)?

5x

To simplify the expression \( (2x + 3x) \), you combine like terms. Like terms are terms that contain the same variable raised to the same power, which, in this case, is \( x \).

When you add \( 2x \) and \( 3x \), you are essentially adding the coefficients (the numerical parts) of the terms together. Here, the coefficients are 2 and 3.

So, you perform the addition:

\[ 2 + 3 = 5 \]

Now, you attach the common variable \( x \) to the result of the addition:

\[ 5x \]

Thus, \( (2x + 3x) \) simplifies to \( 5x \), which is the correct answer.

This concept of combining like terms is fundamental in algebra and is frequently used to simplify expressions, making it easier to work with equations and perform further calculations.
