She would need to buy 75% of the dress Bc 100%-25% is 75%
Area of rectangle = Length*width
A = 28 so 28 = 4 * height
height = 28/4 = 7
Choices:
–8 – 3i
–8 + 3i
8 – 3i
<span>8 + 3i
The additive inverse of the complex number a + bi is -(a+bi) = -a - bi
In this case, a = -8 and b = 3i
a + bi = -8 + 3i
additive inverse is: -(-8+3i) = +8 - 3i
The additive inverse of the complex number -8 + 3i is 8 - 3i. The 3rd choice.

I think that the correct answer is f(-1)=-8 and f(0)=-5
I hope this helps :D
