Complete the problems using the Associative Property.

( X 14) X 3 = 3 X (6 X 14)	17 X (9 X ) = (17 X 9) X 4
X (7 X 4) = (6 X 7) X 4	7 X (4 X ) = (7 X 4) X 44
( X 8) X 17 = 5 X (8 X 17)	(14 X 9) X = 14 X (9 X 23)
( X ) X 11 = 5 X (8 X 11)	( 9 X 14) X 8 = X ( X )
X ( X ) = (7 X 8) X 31	( 4 X 7) X 11 = X (7 X 11)
X (2 X 14) = (18 X 2) X	(5 X 31) X 7 = X (31 X 7)
X ( X ) = (14 X 5) X 8	(0 X ) X 2 = 0 X (7 X )
X (9 X 40) = (6 X ) X	(9 X 14) X 3 = X (14 X )
X (7 X 12) = (10 X ) X 12	(16 X 1) X = 16 X (1 X 6)
X (50 X 9) = (2 X ) X 9	(6 X 17) X = 6 X ( X 5)
X (3 X 5) = (12 X 3) X	(5 X 11) X = 5 X ( X 20)

Complete the problems using the Distributive Property.

(5 X 7) + (6 X 3) = 35 +

( X 4 ) + (3 X 4) = 20 + 12

(10 X 5) + ( X 5) = + 45

( X 2) + (7 X 9) = 18 +

(9 X 3) + ( X 7) = + 21

( X 2) + (7 X 7) = 18 + 49

(9 X ) + (9 X 3) = 72 + 27

( X 8) + (4 X 6) = 40 +

(6 X 20) + (6 X ) = 120 + 54

3 X (8 + 21) = (3 X 8) + (3 X  )

7 X (8 + 5) = ( X 8) + (7 X 5)

X (2 + 4) = (14 X 2) + (14 X 4)

X (3 + 6) = (12 X 3) + (12 X 6)

3 X (19 + 12) = (3 X ) + (3 X 12)

5 X (31 + 5) = ( 5 X ) + (5 X 5)

10 X (17 + 5) = ( X 17) + (10 X 5)

17 X (6 + 4) = (17 X ) + (17 X )

12 X (7 + 8) = ( X 7) + (12 X 8)
