90=0 so therefore the answer is right there 100%
P = 12.
So,
15(12) + 70V < 400
V < (400 - 180)/17
V <3.14
So the max number of video can fit is 3.
Answer:

Step-by-step explanation:
given 
To rationalise multiply the numerator/denominator by the conjugate of the denominator
the conjugate of 3 + 7i is 3 - 7i, hence

distribute the numerator/denominator
=
[ note that i² = - 1 ]
=
