If a cube has a<br> volume of 8 cm<br> what is it's side<br> length?
lana [24]
Side length: 2 cm.

Volume of a cube:
V=a^3
(where V is volume, and a is side length)

If v=8, the formula would now be 8=a^3

Take the cube root of both sides

NEED HELP PLEASE!
USPshnik [31]

Answer:

(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16

Step-by-step explanation:

Complex numbers identity:

The complex numbers identity is:

i^2 = -1

Square of the sum:

(x + y)^2 = x^2 + 2xy + y^2

In this question:

(x + (3+5i))^2

x^2 + 2x(3+5i) + (3+5i)^2

x^2 + 6x + 10xi + 9 + 30i + 25i^2

x^2 + 6x + 9 + (10x+30)i - 25

x^2 + 6x + (10x+30)i - 16

So

(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16
