What is the simplified form of 4x + 4x?

• A. 4x
• B. 8x
• C. 2x
• D. 16x

Answer: (B)

The expression 4x + 4x consists of two like terms, both being multiples of the variable x. When combining like terms, you simply add the coefficients of the like terms together. In this case, you have 4 (from the first term) and another 4 (from the second term). Adding these coefficients gives: 4 + 4 = 8. Since both terms share the same variable, the result will be 8 multiplied by the variable x. Therefore, the simplified form is 8x. This process of combining coefficients of like terms is a fundamental concept in algebra, allowing for a more concise representation of expressions.
