Answer:
Shortest Side = 20 feet
Second Side = 23 feets
Third Side = 37 feets
Step-by-step explanation:
Let the shortest side of the desk be x. Hence,
Second side = (x + 3) feets
Third side = (2x - 3) feets
Perimeter = 80ft
x + (x + 3) + (2x - 3) = 80
4x = 80
x = 20
Hence, Second side = (20 + 3) feets
= 23 feets
Third side = (40 - 3) feets
= 37 feets
Hence<u>,</u><u> shortest side is 20 feets, Second side is 23 feets, Third side is 37 feets.</u>
Let A be the amount of 100% acid.
100A+20*(6)=40*(A+6)
100A+120=40A+240
60A=120
A=2 gallons
