Answer:
8
Step-by-step explanation:
The conjugate of - 2 + 2i is - 2 - 2i, hence
(- 2 + 2i)(- 2 - 2i) ← expand factors using FOIL
= 4 + 4i - 4i - 4i² [ note i² = - 1 ]
= 4 + 4
= 8
The coordinates would be (3,0)
The correct equation would be 21 divided by 7
Given:
The equation is:

To find:
The value of x.
Solution:
We have,

Subtract both sides by
.



Therefore, the value of x is
or it can be written as 0.667.
Answer:
14.29%
Step-by-step explanation:
% Decrease = Decrease/ Original Number × 100
84-72 = 12 (or the amount of the discount)
