Answer:

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
