Okay so, the formula we can use for this problem will be x= 410/.82, x being the original price of the TV. The .82 was figured to make up for the 18% lost from the original price. 410/.82=500. so the original price of the TV would be $500. To check our answer we can multiply 500 by the sale price and subtract that amount from the original $500. Like so: 500-(500*.18)=410.

Answer:
area = 2 + (x-5) * (x-5)
Step-by-step explanation:
area of a rectangle= length * width
length = 2 + (x-5)
width = x-5
-1 (-12 - 9i) + 4i (-12 - 9i)
= 12 + 9i + -48i + 9i^2
= 9i^2 + 39i + 12
