Answer:12
Step-by-step explanation: -7 is in a modulus so it becomes positive and you get 5+7=12
You should research modulus throughly because you'll meet them everywhere especially at complex numbers.
Good luck
Answer:
C
Step-by-step explanation:
Absolute value is always positive because it is the distance from 0. Distance is always positive, so you can cross out D and A.
The distance from -7 to 0 is 7. The distance from 5 to 0 is 5.
7 + 5 = 12, so the answer is C.
Hope this helps :)
