After 18 minutes there will be 486 gallons of water drained.
Given:
The polynomial function is

Yuri thinks that
is a root of the given function.
To find:
Why
cannot be a root?
Solution:
We have,

If
is a root, then the value of the function at
is 0.
Putting
in the given function, we get




Taking LCM, we get


Since the value of the function at
is not equal to 0, therefore,
is not a root of the given function.
When you plug in 3 in for y the equation is 3x + 6(3) = 24
3x + 18 = 24
subtract 18 from both sides
3x = 6
Isolate the x by dividing both side by 3
x = 2

Number 5:
2p^2qx3p^3q^2
Take out the constants (2x3)p^2p^3qq^2
Simplify 2x3 to 6, 6p^2p^3qq^2
6p^2+^3q^1+^2
simplify 2+3 to 5, 6p^5q^1+^2
simplify 1+2 to 3
6p^5 q^3
