D. -4(x+9)
For this you distribute the number outside the parentheses to both numbers inside.
A. 4(x-9)=
4x-36
B. 2(2x-18)=
4x-36
C. -2(2x-18)=
-4x+36
D. -4(x+9)=
-4x-36
Therefore, D is the answer

I believe the answer is going to be 74 students.
You would do vide the numbers
Ex: a sloth travels 5 ft every 10 minutes. you would divide the numbers and the answer would be 2ft/min
which would be 2 feet per minute
Answer:
Step-by-step explanation:
The probability distribution function for uniform distribution in interval [a,b] is given by :_
Given : Mr. Warren Buffet and Mr. Zhao Danyang agree to meet at a specified place between 12 pm and 1 pm.
Since 1 pm comes after 12 pm, and in 24 hours system we call it as 13 pm.
If each person arrives between 12 pm and 1 pm at random with uniform probability, then the uniform distribution function for this will be :_
Hence. the distribution function for the length of the time that the first to arrive has to wait for the other will be :-
