In the expression, the real number a equals 12 and the real number b equals -16.
<h3>How to explain the information?</h3>
It should be noted that the expression given is:
= (4 - 2i)²
Therefore, we need to expand the expression. This will be:
= (4 - 2i)(4 - 2i)
= 16 -8i -8i + 4i²
= 16 -16i +4i²
Substitute -1 for i²
= 16 - 16i + 4(-1)
= 16 - 16i - 4
= 12 - 16i
Therefore, the value of the expression is 12 - 16i.

Answer:
meter and then gallon
Step-by-step explanation:
i hope this helps :)
2 and the 4 needs to add subtract too much
I believe that you are doing multiplication with this.
So… 9 x 3.65 = 32.85
Hope this helps. :)
Answer:

Step-by-step explanation:
We are looking for what number times .50 makes the equation true.
So, just do backwards equation:


Thus, meaning that what multiplied by 0.50 is equal to 17?
[tex]0.50 * 34[tex]
[tex]==> 17[tex]
