Question

Which expression has the same value as the one below?

Answer 1

Answer:

Option A is correct

$12+(-9)$

Step-by-step explanation:

Using associative property:

$a+(b+c) =(a+b)+c$ for any values of a, b and c

Given the expression:

8 + [4 + (–9)]

Apply the associative property we have;

$[8+4]+(-9)$

then;

$12+(-9)$

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

Answer 2

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