Answer:
The expression is not factorable with rational numbers...
Step-by-step explanation:
The answer would be A and B, because they can both be rounded to 180, and are more precise.
If both numbers are negative u add those up and ur answer will be a negative. so number one is negative 9.
if there is more positive ur answer will be a positive. so number 2 is 13.
number is more complicated so negative 3 +4 is 1 because u have more positive and u just subtract those then 1 minus 8 equals negative 7 and negative 7 minus 7 is 0. hope this helps
