Final answer:
The equivalent expression to 3(9p+2r) is found by applying the distributive property, resulting in 27p + 6r.
Step-by-step explanation:
The expression 3(9p+2r) can be simplified by distributing the 3 to both terms inside the parentheses.
This process, known as the distributive property, results in multiplying 3 by each term separately.
Therefore, we get: 3(9p) + 3(2r) Which simplifies to: 27p + 6r
This final expression, 27p + 6r, is the equivalent expression to the original one, 3(9p+2r).
