The answer is A.
First we substitute 8 into the given equation.
Multiply 8 and 5, then find the square root of 40. Finally multiply it by 10.
Then add 15.
And the answer will be 78.245.
Now the question says that s is in thousands, so the real answer would be about 75,000.

Now the question says that s is in thousands, so the real answer would be about 75,000.
Since, it is given that
Now, we have to identify the addition property for the given equation.
Associative property of addition states that for any real numbers say 'a' , 'b' and 'c', a+(b+c) = (a+b)+c
So, in the given question 28+29+42
We can use associative property as
(28+29)+42 = 28+(29+42)
57+42 = 28+71
99 = 99
Hence, among the given properties, associative addition property is used.
