Answer:
1.5n
Step-by-step explanation:
The distributive property can be used to simplify expressions like this (collect terms).
= n(4 -1 +.5 -2)
= n(3 +.5 -2)
= n(3.5 -2)
= n(1.5)
= 1.5n
_____
Of course, you can do the addition in any convenient way. Some like to add all the positive and negative terms, then find the difference.
= n((4 +.5) -(1 +2)) = n(4.5 -3) = 1.5n
A horizontal line goes from left to right on a graph. If a line is horizontal that means that all the values of y will be the same no matter what the x is. In this case all the y - values of this graph will be 9. This makes the equation of the line:
y = 9

Answer:
So in scientific form 4000 miles will be equal to 
Step-by-step explanation:
We have given that radius of earth is 4000 miles
4000 miles can be written as 4×1000
We have to written 4000 miles in scientific form
We know that 1000 can be written in scientific form as 
So 
So in scientific form 4000 miles will be equal to
