Which of the following expressions is equivalent to \(3x(2+5y)\)?
Explanation
Begin by noticing the form in which the answer choices are written. As no answer choice contains a parenthetical expression, start by distributing the 3x through the parenthesis. Multiply 3x by each of the terms inside of the parenthesis and combine any like terms:
3x(2+5y)
= 3x(2) + 3x(5y)
=6x + 15xy
