Given that a cannot = b is it ever possible to have
the sqrt of a + the sqrt of b? Explain.

If either a or b equals zero, then the sums would be the same.

Since the square root of 0 is 0, adding it to a given radical would not change the radical. Also adding zero to the radicand would not change its value.

Explanation:

thnx for the answer

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

the answer is d. 74.02
