It's A because 8-15 is -7 but the absolute value parenthesis make it positive 7.
Do 45/225 and simplify and that’s your answer
x > 7 x < 10
7 o---------------------o 10
This is not an empty set. x contains all of the values between 7 and 10.
This isn’t an answer but we gotta see the question to answer it ☠️☠️
