Answer 1

Given:

Given expression is: 8 + left-bracket 4 + (negative 9) right-bracket

To find:

We need to find the value that represents the given expression.

Solution:

Consider the given expression,

8 + left-bracket 4 + (negative 9) right-bracket

We can write the above expression as,

$\Rightarrow 8+(4+(-9))$

Simplifying the above expression,

$\Rightarrow 8+4+(-9)$

Adding similar terms, we get

$\Rightarrow 12+(-9)$

Now, write the above expression in words.

12 + (negative 9)

So, the above expression matches with option A. So, it will be the required option.

Therefore, option A is correct which is 12 + (negative 9).
