<h3>I'll teach you how to solve (m^2-m-4)+(m+5)</h3>
---------------------------------------------------------
(m^2-m-4)+(m+5)
Remove parentheses:
m^2-m-4 + m+5
Group like terms:
m^2-m+m-4+5
Add similar elements:
m^2-4+5
Add/subtract the numbers:
m^2+1
Your Answer Is m^2+1

Answer:
So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c
T = To + (-3/2°c)x
Where x is the fraction of 4 in hours
Step-by-step explanation:
Its a very simple Expression.
First we consider the first temperature at first time which is 0°c at 12 noon which I initial time, i.e t= 0.
For every four hour change , the temperature adds -3/2°c .
So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c
The expression to know the temperature is
T = To + (-3/2°c)x
Where x is the fraction of 4 in hours
