Part A: 42° < x < 176°
Part B: See Explanation
Part C: No
Step-by-step explanation:
PART A:Required temperature of benzene to ensure it remains liquid = x
Boiling temperature= 176°F
Freezing Temperature= 42°F
So the inequality can be written as:
42° < x < 176°
PART B:(GRAPH IS ATTACHED)
The Red shaded region represents all the possible value.
The Red Open circles represent boundaries of the solution. The values not included in the solution
PART C:As it is necessary for benzene to stay in liquid form for the research, it should always stay above 42°F.
If the temperature of the building fell to 20°F , research cannot be conducted as benzene will freeze.
