Which of the following correctly demonstrates the Associative Property of Addition?
Responses
(x+y)+z+r=x+(y+z)+r
y−(x+1)=(y−x)+1
x⋅(y+z)=(x⋅y)+z
m⋅(x⋅y)=(m⋅x)⋅y
(x+y)+z+r=x+(y+z)+r correctly demonstrates the Associative Property of Addition.
The option that correctly demonstrates the Associative Property of Addition is:
(x+y)+z+r = x+(y+z)+r
