3 \sqrt{-8}  + 4 \sqrt{-50}
= 3i \sqrt{8}  + 4i \sqrt{50}
= 3i \sqrt{4 \times 2}  + 4i \sqrt{25 \times 2}
= 6i \sqrt{2}  + 20i \sqrt{2}
= 26i \sqrt{2}

I think part of the second question is cut off so I can't help but I hope I have helped with the first one.

A cuboid in which the sum of its dimensions is 9 cm., then the sum of its edge lengths - cm. (18 or 27 or 36 or 45)​
ser-zykov [4K]

The number of sides or edges on a cuboid  are twelve, and the sum of the

edges is the sum of the twelve edges.

The sum of the edge lengths = <u>36 cm</u>

Reasons:

The given parameters are;

The sum of the dimension of the cuboid = 9 cm

Required:

The value sum of the dimension of the edges the cuboid.

Solution:

The dimensions of a cuboid are; Length, <em>l</em>, width, <em>w</em>, and height, <em>h</em>

We get;

l + w + h = 9

The number of times that each dimension appear = 4 times

4 edges with the same length as the height, <em>h</em>

4 edges with the same length as the width, <em>w</em>

4 edges with the same length as the length, <em>l</em>

The sum of the edge lengths is therefore; Sum Edges = 4·l + 4·w + 4·h

Which gives;

Sum Edges = 4·l + 4·w + 4·h = 4 × (l + w + h) = 4 × 9 = 36

The sum of the edge lengths = <u>36 cm</u>.
