The left side of this equation is already a perfect square: <span>x^2-10x+25=35.
Rewriting it, we get (x-5)^2 = 35.
Taking the sqrt of both sides, x-5 = sqrt(35).
Solving for x: x = 5 plus or minus sqrt(35) (answers)</span>

Answer:
The will be 27000 bacteria in 36 hours from the start of the experiment
Step-by-step explanation:
In the first 18 hours:
The number of bacteria grew from 30 to 900.
So it grew by a factor of 900/30 = 30.
36 hours from the start of the experiment:
That is, the next 18 hours.
It will also grow by a factor of 30.
From 900 to 900*30 = 27000
The will be 27000 bacteria in 36 hours from the start of the experiment
Z=k/x
2=k/3
k=6
k is constant so it will remain 6 now subsitute 13 in equation and solve
z=6/13
