Answer:
let the time be "x" minutes for both
after x minutes,
the first pool will have 1660l + 30.75x
and the second pool will have 1900+ 23.25x
note: both pool Will have equal volume of water
1660+ 30.75x=1900+23.25x
30.75x-23.25x= 1900-1660
7.5x=240
x = 240/7.5
x= 40minutes
Answer:
No.
Step-by-step explanation:
If any x value (left to right) is repeated (as shown by having a line over it multiple times) the answer is not a function.
Answer:

Answer:
7m^4-52m^3-28m^2+67m+42
Step-by-step explanation:
(7m^2-3m-7)(m^2-7m-6)
7m^4-3m^3-7m^2-49m^3+21m^2+49m-42m^2+18m+42
7m^4-3m^3-49m^3-7m^2+21m^2-42m^2+49m+18m+42
7m^4-52m^3-28m^2+67m+42
