Answer:
B) 6(5x -2y)
Explanation:
When we have a number outside the parenthesis, we can distribute this number to all the terms inside the parenthesis. Since our given expression is 30x -12y, we are looking for an expression that when expanded results in these two numbers.
Only option B provides both 30x and -12y, as seen as 6 times 5x= 30x and 6 times -2y = -12y.
