Find the additive inverse of -7+5i.

Required additive inverse is .

Step-by-step explanation:

Given number is .

Now we need to find about what is that additive inverse of the given number .

We know that if complex number is then it's additive inverse is given by .

Basically we need to change the sign of imaginary term.

imaginary term in given number is +5i.

Changing sign of +5i gives -5i.

Hence required additive inverse is .

c. 4 and 1/2 pounds is the answer! : )

the discriminant is 64 + 4*1*12 = 112

this is prime.
