Answer:
a. 
b. 
Step-by-step explanation:
You need to remember that:
1. The word "more" indicates Addition.
2. The "Difference" is the result of a Subtraction.
a. Then, knowing this information, you know that:
- "The difference of 
and 
" must be expressed as:
- Then, "Three more than the difference of and " is:
- "The difference of 
and 
" can be expressed in this form:
Therefore, "Three more than the difference of and is equal to the difference of and " is:
b. Solve for "s" in order to find its value:
Answer:
x= 3 inch should be turned up on each side
Step-by-step explanation:
Let the height of trough be x.
Width of trough be 12 - 2x.
and length of trough = 120 inch
Volume of trough, V = L×W×H = 120 × (12-2x) × x = 120x(12 - 2x)
For maximum volume, we find V' = 0
i.e 1440 -480x = 0
or x = 
or x= 3
Hence x= 3 inch should be turned up on each side
