Answer:

$\boxed{ \bold{ \huge{\boxed{ \sf{ - 3i + 1}}}}}$

Step-by-step explanation:

$\sf{(4 + 2i) + ( - 3 - 5i)}$

When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign.

That means the expression remains the same.

Just remove the parentheses

$\sf{4 + 2i - 3 - 5i}$

Collect like terms

⇒ $\sf{ - 3i + 4 - 3}$

Calculate the difference

⇒ $\sf{ - 3i + 1}$

Hope I helped!

Best regards!!

Answer:

~8.66cm

Step-by-step explanation:

The length of a diagonal of a rectangular of sides a and b is

$\sqrt{a^2+b^2}$

in a cube, we can start by computing the diagonal of a rectangular side/wall containing A and then the diagonal of the rectangle formed by that diagonal and the edge leading to A. If the cube has sides a, b and c, we infer that the length is:

$\sqrt{\sqrt{a^2+b^2}^2 + c^2} = \sqrt{a^2+b^2+c^2}$

Using this reasoning, we can prove that in a n-dimensional space, the length of the longest diagonal of a hypercube of edge lengths $a_1, a_2, a_3, \ldots, a_n$ is
