Use the associative property to identify which expression is equal to (21)(7)(3x). (21 x 7 x3) x (7)(21)(3x) 32(7 + 3x) (3x)(7)(21)<----my answer

hmm assuming that a = 21, b = 7, c = 3x 21 x (7 x 3x) = (21 x 7) x 3x but hmm there's gotta be one not in the parenthesis and that's what is throwing me off.

A associativve property refers to the changing the order regardless of the parenthesis A is the only one which puts a number out of the brackets i'd go A
anonymous

UsukiDoll
  • UsukiDoll

Jack1
  • Jack1
