Points A, B, and C form a triangle. Points A and B are shown on the coordinate plane below. Point C is a reflection of

Answer:
The answer is given below
Step-by-step explanation:
Given that:
Point A = (-4,3) and point B = (2,3)
Since Point C is a reflection of point B across the x-axis, point C has the same x coordinate as point B but the value of the y coordinate is the opposite sign. Therefore the coordinate of point C is (2,-3). The distance between AB is given as:
The height of the triangle is BC and the base is AB. The area of triangle ABC is given as:
Area = 1/2 × base × height = 1/2 × 6 × 6 = 18 unit²

To get the answer, you need to think of it like a see-saw.
Both sides must equal the same relative to 33.5. For example, 32 is 1.5 away from 33.5 so you could say you have 1.5*4 (because theres 4 tubes with 32 sweets). If you were to do this for the whole table, it would look something like this:
This simplifies to:
This method can sometimes be inefficient depending on how many values but is probably the simplest way to solve this problem.
hope this helps :)
(sorry the other way is kinda hard to explain possibly ask your teacher tomorrow)
