Question

Which algebra expression is represented by the model 3(3x+9)

Answer 1

9x + 27 is a binomial. (Two terms)

Explanation:

3(3x + 9) = 9x + 27

Answer 2

The algebraic expression represented by the model 3(3x+9) is:

\[3 \cdot (3x + 9)\]

This expression can be simplified by distributing the 3 into the terms inside the parentheses:

\[9x + 27\]

So, the simplified algebraic expression is 9x + 27.
