Answer:
Min
Step-by-step explanation:
To check if it has a max or min, you must reference the a value. The a value in this case is 2, and that is positive. Positive parabolas point up, so they can only have a minimum point.
The answer is 0.04444... or 2/45. Whichever is more useful to you.
Let w be the width of the deck. Then, using the total area, we get:
(9+2w)(18+2w)=400
4w²+54w-238=0
2w²+27w-119=0
(2w-7)(w+17)=0
w=-17 or 7/2
Using the positive value, we get a width of 3&1/2 ft. for the deck

Answer:
A/ 3.14a=b
Step-by-step explanation:
A=3.14ab
Divide each side by 3.14 a to isolate b
A/ 3.14a=3.14ab/3.14a
A/ 3.14a=b
