B. –12 + 9
C. –4 + (–9)
D. 4 + (–9)

Respuesta :

8 + [4+(-9)] = 3
A. 12 + (-9) = 3
Therefore the correct answer is A. 12 + (-9)

Answer:

Option A is correct

[tex]12+(-9)[/tex]

Step-by-step explanation:

Using associative property:

[tex]a+(b+c) =(a+b)+c[/tex] for any values of a, b and c

Given the expression:

8 + [4 + (–9)]

Apply the associative property we have;

[tex][8+4]+(-9)[/tex]

then;

[tex]12+(-9)[/tex]

Therefore,  the expression has the same value as 8 + [4 + (–9)] is, [tex]12+(-9)[/tex]
