For this case we have the following functions:

The first thing we must do for this case is to subtract both functions.
We have then:

Substituting we have:

Rewriting we have:

Evaluating the obtained function for x = 3 we have:

Answer:
The value of the function evaluated at x = 3 is:

Answer:
Step-by-step explanation:
The factors are 1 2 3 4 6 and 12
<h3>
17) 5ft</h3>
In order to do this problem you must use square roots. Basically the same number multiplied twice to get your answer. In this problem, 5 * 5 = 25.
<h3>
18) 10m</h3>
Since they are asking for the square root to the nearest whole unit, we must know that the √105 lies in between 10 and 11, since 10 * 10 = 100 and 11 * 11 = 121. 105 is closer to 100 than it is to 121 and therefore the answer is 10.
Don't forget your labels!!! (Feet and meters)
Z=9 so 3*9 is 27. 27 is your answer. You are literally just switching the variable z with 9.
The answer is A, let me know if you need an explanation
