Yes rational expression and its simplified forms are equivalent.
Rational expression are those that contain fractions.
Example:
25/50 is a rational expression but it is not yet in its simplest form.
25/50 ⇒ 5/10 ⇒ 1/2
1/2 is the simplest form of 25/50.
They are equivalent:
1/2 = 25/50
1*50 = 2*25
50 = 50
or
1/2 = 0.50
25/50 = 0.50
Did you ever figure this out? I need help with exams 3-5 I have the other answers. Let me know if you want to help each other.
Answer:
27
Step-by-step explanation:
1^3 = 1
2^3 = 8
3^3 = 27
4^3 = 64
5^3 = 125
The missing number is 27.
Solution :
1). The cost of the formula is given as :
$ 19,350 + $12 x
2). 95%
for the prediction is :


(rounding off)
3). r = 0.92
Therefore, 
That is 84.64 % of the variability in the moving cost is best explained by the number of moves.
