Answer:
.
Step-by-step explanation:
Let the volume of this cistern be .
The first pipe fills the cistern at a rate of .
In other words, each hour, the first pipe would fill of the cistern every hour.
On the other hand, the second pipe fills the cistern at a rate of .
This pipe would fill of the cistern every hour.
Hence, when opened together, the two pipes would fill of this cistern every hour.
At this rate, it would take for the two pipes to fill the entire cistern.
f(x) = (x – 7)(x – 5)(x – 5)(x + 2) should be your answer
To get the x, -2, 7, 5 and 5, you must first place each parenthesis = to zero. Solve for x.
x - 7 = 0, x - 7 (+7) = 0 (+7), x = 7
x - 5 = 0, x - 5 (+5) = 0 (+5), x = 5
x - 5 = 0, x - 5 (+5) = 0 (+5), x = 5
x + 2 = 0, x + 2 (-2) = 0 (-2), x = -2
