Answer:
(a) Side lengths

(b) Slope

(c) Scalene triangle
Step-by-step explanation:
Given



Solving (a): Length of each side
This is calculated using distance formula

So, we have:






Solving (b): The slope of each side
This is calculated using:

So, we have:








Solving (c): Classify the triangle
In (a), we have:



None of the sides are equal;
The triangle is scalene
Your total profit is $13,000. First you bought the 200 items for $20 each. That costs $4,000. Then you sold $50 of the items at $100 each. That’s $5,000. So already you’re in the green. You’ve already made $1,000 profit. Then you sold the rest of the items at a 20% discount. 150 items multiplied by $80 is $12,000. $12,000 plus the $1,000 equals $13,000 total.
