Answer:An absolute value inequality is solved by re-writing it as compound inequality. For example.
|x+1| < 5
Since the value inside the absolute value brackets: (x+1) can be positive or negative, it is re-written as a compound inequality as the example below.
x+1 < 5
x+1 > - 5
solve for the range of values x can be
-6 < x < 4
Step-by-step explanation: How to solve inequalities
Yes it is right because you are measuring by either the base to height or length times width

From the question we are told that:
Demand point 
Supply Point 
Generally the equation for fixed-requirement constraints is mathematically given by



Therefore the correct option is
Option B
Answer:
(x+13)2.3 if simplifying.
Step-by-step explanation:
sum means add. so x plus 13 times 2.3 or 2.3(x+13)
