Let width = x, then length = 3x - 2.
So we have area = width * length = x * (3x + 2)
A = 3x² + 2x

Now we need to find A(2) = 3 * 2² + 2 * 2 = 16ft²

Separate them first.
7+8=15
5/6+2/6=7/6
There can't be 7/6, so it becomes 1 and 1/6,
15+1+1/6=16 1/6

The interval​ time, I, in​ minutes, between appointments is related to total number of minutes T that a doctor spends with patie
zmey [24]

Answer:

Approximately 5.19 hours.

Step-by-step explanation:

The question is asking that you solve for T (the amount of time spent with patients in a day). To do so, simply input the values which it has given you for your variables. We can substitute 16 for I as that is the doctor's preferred interval time and we can substitute 21 for N as that is the amount of appointments the doctors wishes to have per day.

16=1.08(\frac{T}{21} )

To solve, start by multiplying both sides by 21.

336=1.08T

Next, divide both sides by 1.08.

311.11=T

Your answer comes out to 311.11 minutes. The question is asking for this to be translated into hours per day, which equates to approximately 5.19 hours.
