identify structure what expression, in factored form, is $3x(3 + 7y)$?
Answer
Explanation:
Step1: Analyze the given expression
The given expression (3x(3 + 7y)) is already in factored form. Factored form means expressing an algebraic expression as a product of its factors. Here, (3x) is one factor and ((3 + 7y)) is the other factor.
Answer:
(3x(3 + 7y))
