X= width of the path.
we can suggest this equation:
(20+2x)(28+2x)=1584
we solve this equation:
(20+2x)(28+2x)=1584
560+40x+56x+4x²=1584
4x²+96x-1024=0
4/4x²+96/4x-1024/4=0/4
x²+24x-256=0
We solve this square equation:
x=[-24⁺₋√(576+1024)]/2=(-24⁺₋40)/2
we have two solutions:
x₁=(-24-40)/2=-32 this solution is not valid.
x₂=(-24+40)/2=8
Answer: the width of the path is 8 m.
2 x 18 = 36
5 x 18 = 90
36 + 90 = 126
the coach should order 126 rolls of tape

Answer:
63.829 or 63.83
Step-by-step explanation:
60 divided by 94
There are 4 quarts in a gallon, so multiply 20 x 4 to get 80.
The aquarium can hold 80 quarts.
Hope I helped!
