Which expression illustrates the associative property of addition? (3 + 19) – 12 = (3 + 12) – 19 3 + (19 – 12) = 3 + (19 + 12) (3 + 19) – 12 = 3 + (19 – 12) 3 + (19 –12) = 3 – (19 + 12)

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
