–(z + (–17)) = 12 + 17

B.

–12








C.

12








D.

46

Answer 1

\[-(z+(-17))=12+17\]Plug in any of the answer choices for z. \[-(-12+(-17))=12+17\] Distribute the negative. \[12+17=12+17\] Which equals: \[29=29 \]
So the answers is -12. Just plug each number in for z and see if it is equal on both sides.
