Respuesta :

The expression was written using the associative property of addition.

[(-2) +8] +3 equals 6 + 3 which equals 9.

(-2) + [8+3] equals (-2) + 11 which equal 9.

Given,

[(-2) +8] +3 equals ______ + 3 which equals _____  

(-2) + [8+3] equals (-2) +  _____  which equal _____

We need to see which operation is used and fill in the blanks.

What is the associative property of addition?

It states that (a+ b) + c = a + (b + c).

We have,

[(-2) +8] +3 equals ______ + 3 which equals _____  

(-2) + [8+3] equals (-2) +  _____  which equal _____

We can write it as:

[(-2) +8] +3  = 6 + 3 = 9

(-2) + [8+3] = -2 + 11 = 9

We see that,

[(-2) +8] +3 = (-2) + [8+3]

This is in the form: (a+b)+c = a+(b+c)

Thus the expression was written using the associative property of addition.

[(-2) +8] +3 equals 6 + 3 which equals 9.

(-2) + [8+3] equals (-2) + 11 which equal 9.
