Answer:

7

Step-by-step explanation:

An<em> "additive inverse"</em> refers to a number that when added to a specific number equals to <em>"zero."</em>

In the question above, the additive inverse of -7 is 7 because:<u> -7 + 7 = 0</u>

Other examples:

1. The additive inverse of 2 is -2 because: 2 + (-2) = 0

2. The additive inverse of -100 is 100 because: -100 + 100 = 0

3. The additive inverse of \frac{1}{2} is -\frac{1}{2} because: \frac{1}{2} + -\frac{1}{2} = 0

Help, please! Struggling!
MArishka [77]

Answer:

65

Step-by-step explanation:

(4-7i)(4+7i) =16 + 28i-28i -49i^2 ➡16 - 49i^2

16 + 49 = 65

the fault here is i^2= -1 and -1 multiplied by -49 is +49 not -49
