Answer:
2i√5
Step-by-step explanation:
√-20 = √-1 × √20
√-1 = i
√20 = 2√5
i × 2√5 = 2i√5
V = l x w x h
96 = l x w x 8
divide both sides by 8
12 = l x w
the rectangular prisms other dimensions would be any positive combination of numbers that multiplies to 12. <span />
The cylinder is a clue to use cylindrical coordinates. Taking

and

, we then are forced to use

. So the parameterization of the intersection of the plane and cylinder is

To get the surface, we can introduce a second parameter

that "contracts" the elliptical intersection to a point. The simplest way to do this is to use

with

and

.
The answer to this should be a-8b+13c
a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]}
=a - {4b - [a - 5b + c + 3c - a + b + 9c]}
=a - {4b - [- 4b+ 13c]}
=a - {4b + 4b -13c}
=a - 8b + 13c
Hope this helped :)
Have a great day
