(f+g)(x) is simply saying add these two problems together.
(2x+6) + (4x^2)
Parenthesis are now useless, as there is only addition.
2x + 6 + 4x^2
Reorder, cause it's pretty and familiar
4x^2 + 2x + 6
We could further simplify
2(2x^2 + x + 3)
You can't really determine the amount of computers from this question, they're obviously not going to have one computer for everyone so half third, or even a fourth of the school population
Answer:
Changing the net force on an object can either impress on it even more force in the direction that it is moving, making it go faster, or if you apply more net force on the object against it, then it decreases acceleration
Step-by-step explanation:
Answer:
A= Q/d +N
Step-by-step explanation:
First you want to move the d term over by dividing both sides
Next you can move the N over by adding it to both sides.
Answer:
Mean = 15
Standard deviation = 1.94
Step-by-step explanation:
We are given the following information:
We treat favoring of building a police substation as a success.
P(Success) = 75% = 0.75
Then the number of citizens follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 20
We have to find the mean and the standard deviation.

Thus, the mean of favoring the substation is 15 and the standard deviation of favoring substation is 1.94
