Question

Which expression would be easier to simplify if you used the associativeproperty to change the grouping?O A. (60 + 40) + (-27)O B. (2+ 3) + (-2)O c. [(-0.2) + (-0.6)] +1.7O D. 6+ (6 +(-3)

Answer 1

the associative property for sums is the next

`(x+y)+z\text{ = x+(y+z)}`

In this case, if you see the letter B. you can use the commutative property and then the associative property to cancel the number 2, that is

`(2+3)+(-2)\text{ = (3+2)+(-2) = 3+(2+(-2))=3+0=3.}`

This is the only option where you can do that.
