B. -17-5
Explanations:Note that:
- a - (-d) can be written as:
1) -a + d ( because minus times minus is plus)
2) d + (-a) because - a + d is equivalent to d + (-a)
3) d - a (because - a + d can also be written as d -a )
Therefore:
-17 - (-5) can be written as
5 + (-17) = 5 - 17 = -12
-17 + 5 = -12
The only incorrect choice is -17 -5 because it is the only option that gives -22 rather than -12
