Question

Which expression is an equivalent expression of 12x + 10 + 4y? 2(6x + 2y + 6) 3(4x + y + 10) 2(6x + 4y + 8) 2(6x + 5 + 2y)

Answer 1

12x + 10 + 4y is equivalent to
2(6x + 5 + 2y).

This is because
2(6x + 5 + 2y) =
2 * 6x + 2 * 5 + 2 * 2y =
12x + 10 + 4y

Answer 2

12x + 10 + 4y= 2(6x + 5 + 2y)

Multiply it out
=2(6x + 5 + 2y)
distribute 2 to every term in parentheses
=(2*6x) + (2*5) + (2*2y)
=12x + 10 + 4y

ANSWER: Last choice 2(6x + 5 + 2y)

Hope this helps! :)
