which of the following expression represents the statement?

Question

two times the sum of a number and 9

Answer 1

The expression that represents the statement "two times the sum of a number and 9" can be expressed mathematically as:

\[ 2 \times (x + 9) \]

Here, \( x \) represents "a number." The expression inside the parentheses, \( x + 9 \), represents the sum of the number and 9, and multiplying this sum by 2 gives you "two times the sum."
