\( 1 \leftarrow \left\lvert\, \begin{array}{c}\text { Multiply. } \\ 9 \times(2 x+5) \\ 9 \times(2 x+5)=\square \text { (Simplify your answer.) }\end{array}\right. \)

To solve \( 9 \times (2x + 5) \), you will use the distributive property, which means you multiply 9 by each term inside the parentheses. So, it goes like this: \( 9 \times 2x = 18x \) and \( 9 \times 5 = 45 \). Combining these results gives you \( 18x + 45 \). Thus, \( 9 \times (2x + 5) = 18x + 45 \). Multiplying expressions with variables might seem tricky at first, but just remember the distributive property is your friend! A common mistake is to forget to multiply both terms inside the parentheses. Always double-check to ensure that you've addressed each term; you'll avoid mistakes and increase your confidence in algebra!
