Answer:
3/4 times 18= 13.5
31.5-13.5=18
It cost 18 dollars for the skirt with a discount.
It cost 13.5 for the blouse as opposed to the original price of 18 dollars.
18(skirt)+13.5(blouse)=31.5
If you set up a proportion to find the original price of the skirt you will get the answer.
18/x=75/100
75x=18 times 100
75x=1800
75x/75=1800/75
x=24
The original price of the skirt is 24 dollars.

Step-by-step explanation:
If -4 + 5i is a root of a polynomial, then it's conjugate -4 - 5i will also be a root of the same polynomial.
Therefore, the polynomial has 4 degree, and zeroes are (- 4 + 5i), (- 4 - 5i) and -1 with multiplicity 2.
Hence, the polynomial will be

⇒ ![f(x) = [x^{2} + 8x + (4 - 5i)(4 + 5i)] (x + 1)^{2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Bx%5E%7B2%7D%20%2B%208x%20%2B%20%284%20-%205i%29%284%20%2B%205i%29%5D%20%28x%20%2B%201%29%5E%7B2%7D)
