Answer:
a. 29
b. 9.1
Step-by-step explanation:
General = The perimeter is all the sides added togther.
a. x is given to you, so you just add all the numbers.
b. Now the perimeter is given, but not x. So add the numbers you can see. That would be 9+6.5+4.7= 20.2
So something + 20.2 has to equal 29.3
29.3 - 20.2 = 9.1.
I did not answer c. because I'm not very confident that my answer would be right. With my explainaion I hope you can figure it out easily enough. Good Luck!

Answer:
The rate of change was 3.5 degrees / h.
Step-by-step explanation:
In order to calculate the rate of change we need to divide the variation of temperature by the variation of time. Since the time is given to us in a 12 h format (am/pm), we first need to convert it to 24 h. To do that we sum the time that is "pm" by 12, we have:
time2 = 3 + 12 = 15
Therefore the rate of change in temperature is:
rate = variation of temp / variation of time
rate = (temp final - temp init) / (time final - time init)
rate = (82 - 54) / (15 - 7) = 28 / 8 = 3.5 degrees / h
The rate of change was 3.5 degrees / h.
Equations don't have minimum or maximum, functions do.
Function y=2n^2+5n-25 has minimum -28.125, has no maximum.
