I would say C. and A. Hope this helps.
Step-by-step explanation:
The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.
we see that the visible 7 numbers have a range of 50-17 = 33.
that means that x has to make sure that the range really is 69.
so, we have indeed 2 choices : x can be the lowest value (with a difference of 69 to the highest value, 50), or x can be the highest value (with a difference of 69 to the lowest value, 17).
x as the lowest value :
x = 50 - 69 = -19
x as the highest value :
x = 17 + 69 = 86
Answer:
2x-6
I don't know what you mean by correction, but that's in expression form.
Let X be the variable used to represent the expression of the total number of books that Mario has read.
We used 4X to represent "four times the number of books". Then we add -2 to interpret the words "for two less than".
Therefore, we have an expression of 4X-2 for the total number of books that Mario has read.
Answer:
15.9 centimeters
Step-by-step explanation:
the information we have is:
Perimeter: 
Number of sides of the polygon: 
since each side has equal length, we can use the following equation to find the measure of one side of the polygon, the equation for perimeter:
where n is the number of sides and 
is the length of each side.
So we clear for and we get:
and subtituting the known values:
each side is 15.6 centimeters long
