9(2x + y)
18x+9y
To simplify 9(2x + y), we can use the distributive property of multiplication over addition. This property states that when a number outside of parentheses is multiplied by an expression inside the parentheses, that number should be multiplied by each individual term inside the parentheses.
Applying this property to our expression, we get:
9(2x + y) = 9 * 2x + 9 * y
Simplifying further, we get:
18x + 9y
Therefore, the simplified form of 9(2x + y) is 18x + 9y.
