Option C: (x+4) and (x-1) are the factors of the equation
Explanation:
Given that the equation is 
We need to determine the factors of the equation.
Splitting the middle term, we get,

Grouping the terms, we have,

Let us factor out the term (x+4), we have,

Thus, the factors of the equation are (x+4) and (x-1)
Hence, Option C is the correct answer.
If you already picked one wrong door then it is a 50/50 chance you will get the correct door or 1/2 or 1 of 2 or .5
Answer:
Step-by-step explanation:

Equation:

2y - 2*9 = 15(x - 4)
2y - 18 = 15x - 60
2y - 18 + 60 = 15x
2y + 42 = 15x
15x - 2y = 42
No he is wrong there will be 150000000 bacteria on it at 2 minutes
WORK:
2 min=120 sec
120 divided by 15=8
15 times 10 (7 times)
u get 150,000,000
