Which of the following shows 2 + (x + 3y) rewritten using the Associative Property of Addition?

Paha777 [63]

B (2+x) +3y

Other examples include (14 + 6) + 7 = 14 + (6 + 7)
because Adding 14 + 6 easily gives the sum of 20 to which we can add 7. The right hand side of the equation is where we add 14 and 13. Both sides will result in 27.
