Explanation:

Operating cash flow -

It helps to estimate the amount or number of cash which is produced via any company during its normal business operations .

If any company can produce a  positive cash flow or not is indicated via operating cash flow .

Hence , the correct definition for operating cash flow is ( B ) .

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this

its kinda hard to answer this when we dont have all the information that we need.
