Expand and simplify (3x + 2)(x + 9)

Final answer: To expand and simplify the expression (3x + 2)(x + 9), we use the distributive property and combine like terms to get the simplified form. Explanation: To expand and simplify the expression (3x + 2)(x + 9), we need to use the distributive property. This property states that when we multiply a term by a sum, we can multiply each term inside the sum individually and then add the results. Applying this property: 3x * x = 3x^2 3x * 9 = 27x 2 * x = 2x 2 * 9 = 18 Combining these results, we get: (3x + 2)(x + 9) = 3x^2 + 27x + 2x + 18 Simplifying the expression further: (3x + 2)(x + 9) = 3x^2 + 29x + 18 Learn more about Expanding and simplifying algebraic expressions here: brainly.com/question/35412911
