I don’t think anyone knows this one not even James
Sara has completed the 50m freestyle in 27.47 seconds and Hannah finish the course in 28.68 seconds.
now the question is asking us how to find a difference between those stats so what we do is find the difference between Hannah and Sarah
Answer:
The answer is B. 30 seconds
I always start by moving the last term to the other side
To complete the square you take term 'b' , divide it by 2 then square it
= 25
We have to add 25 to what we have and what you do to one side you have to do to the other
Now we factor what is on the left side of the equation
The last step is to move our right side of the equation back over
- which is your answer :)))
