b.)the answer is 2x+7y-9
c.)the answer is 24x+48
d.)the answer is 24x+6
e.)the answer is 5x+9
Answer:
D is correct. 
Step-by-step explanation:
We are given the root of the equation

If we are given solution of the equation then find equation using formula.
If a and b are the solution of equation then equation would be (x-a)(x-b)=0
Here, 
Equation form would be 
Now we simplify the above equation to get correct option.


So, D is correct. 
Since it is stated that the machine he bought only predict about 80%. Thus, about 20% are still possible that there are oils in the land that he owned.
In a 100% value = 80% were the 0 possibillites detected by the machine and 20% are still the possibility that it has an oil.
=> 80% = 0.80
=> 20% = 0.20
In the given choices. letter B has the closest value to the 20% that we expected.
Thus, let's have B as an answer.

so this means x = 1</span></span>
