Step-by-step explanation:
To compute x times y must use foil on the right hand side.
First: 
Outer: 
Inner: 
Last: 
------------------------------------Add like terms:
----------------
Multiply top and bottom by bottom's conjugate:
Foil the top and just do first and last of Foil for the bottom since the bottom contains multiplying conjugates:
Replace 
with -1:
Both equations are correct. x= 37. plugging in 37 for x gets the right answer for both. 44-(37)=7 and (37)+7=44. Another equation you could use is 44-7=x... which makes x = 37. does that make any more sense than my last response? I hope so.
Answer:
300-400
Step-by-step explanation:
The first step is finding the total of the data we have. So, we take 5 + 10 + 15 + 20 + 25 + 15 + 10 which equals 80.
The median is the middle point of all the data. If it's an odd number, you can calculate the median with the equation (n+1) / 2, plugging in the total amount of data for n.
When it's an even number though, there is no one middle point since the data splits evenly in 2, so we have to use 2 equations: n/2 & (n/2) + 1. Then, we find the average of those two data points. (Although, you don't have to do that for this particular question).
When we plug 80 in for n in both of these equations, we get 40 and 41.
To where this is in the question, we have to count up from the bottom of the chart. 1-5 is below 100, 6-15 is 100-200, 16-30 is 200-300, and 31-50 is 300-400.
Since 40 and 41 are between 31 and 50, the answer is 300-400.
Hope this helps! :)
