Answer:

2

Explanation:

Given:

  • a + b = -5

To find -a - b

Factor out the common term -1:

⇒ -a - b = -(a + b)

Substitute a + b = -5:

⇒ -a - b = -(-5)

Apply rule -(-x) = x:

⇒ -a - b = 5

Therefore:


\begin{aligned}\implies \sf (|a+b|+5)/(|-a-b|) & = \sf (|-5|+5)/(|5|)\\\\& = \sf (5+5)/(5)\\\\& = \sf (10)/(5)\\\\& = \sf 2\end{aligned}

Note: |-x| = x
