Jakob is asked to simplify the expression –3a + 4b + 5a + (–7b). He writes: –3a + 4b + 5a + (–7b) = –3a + 5a + 4b + (–7b). Which property allows him to do this? the associative property the commutative property the distributive property the additive identity property @Vocaloid @Ultrilliam @beebo31 @sazzie @thisgirlpretty
