Unit rate because unit is referring to one so for example for every unit, there are 6 apples. The unit in the case would be a box
The solution depends on the value of

. To make things simple, assume

. The homogeneous part of the equation is

and has characteristic equation

which admits the characteristic solution

.
For the solution to the nonhomogeneous equation, a reasonable guess for the particular solution might be

. Then

So you have


This means


and so the general solution would be
4/5 / 2/5
= 4/5 * 5/2
= 4/2
= 2
Answer: 2 pages per hour
A=27.18
There is a photo showing the answer and the formula and stuff hope this helps
Steps:
(n-2) * 180 = sum of interior angles
(3-2) * 180 = 180
Bottom Triangle
25 + 51 + x = 180
x = 104
Top Triangle
104 + 34 + x = 180
x = 42
Answer:
42
