Please post the question, so that people like me who do not have access to questions can still analyse the same and try to answer them.

The expression in your document can be re-written as Sqrt((x+3)^2) + Sqrt((y-1)^2)
Which employs => (x+3) + (y-1) we need to find value of this expression
When x = 3/4 and y = 2/5
3/4 + 3 + 2/5 - 1 = (15 + 60 + 8 - 20)/20 = 63/20
Answer B

(x+3) + (y-1)
but its not addition as per the question - its subtraction.
