Since telecommuting has become more common, workers have needed to develop communications skills that a. are clear and even in tone b. do not depend on face to face contact c. cut across multiple formats d. all of the above

Correct Answer, D all of the above. Each answer is a positive source of communication for telecommuters.

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
