Question

Given a = -3 and b = 4 and c = -5, evaluate |c - a - b|.
2
4
6

Answer 1

-5--3-4
when there are two negative signs beside each other you change it to a plus sign
so:
-5+3-4

Answer 2

C. 6

Explanation:

We are asked to evaluate the expression
`|c-a-b|` for given values.

To evaluate our given expression, we will substitute
`a=-3`,
`b=4` and
`c=-5` in the given expression as:

`|(-5)-(-3)-4|`

Using property
`-(-a)=a`, we will get:

`|-5+3-4|`

`|-5-4+3|`

`|-9+3|`

`|-6|`

Using property
`|-a|=a`, we will get:

`|-6|=6`

Therefore, the value of given expression is 6.
