<span>The vertex of the parabola is the highest or lowest point of the graph.
</span><span>y=-4x^2+8x-12 = -4 (x^2 -2x +3)
Lets work with this now: </span>x^2 -2x +3
x^2 -2x +3 -> what is the closeset perfect square?
x^2 -2x +1 = (x-1)^2
So
x^2 -2x +3 = (x-1)^2 +2
Replacing to original
y=-4x^2+8x-12 = -4 (x^2 -2x +3) = -4 ((x-1)^2 +2) = -4 (x-1)^2 - 8
The min or max point is where the squared part = 0
So when x=1 , y= -4*0-8=-8
This will be the max of the parabola as there is - for the highest factor (-4x^2)
The max: x=1, y= -8
Times the two to get your answer.

Answer:
phythaforean theorem:
1 . The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
2. Find the square root to find the accurate length of the hypotenuse.
distance formula:
1. The distance formula is used to determine the distance, d, between two points.
distance = speed × time
Formula- d= √x2-x1)²+(y2-y1)²
2. It's used for :
-Finding the perimeter of polygons
-Finding the area of rectangles
-Finding the equation of a circle
Answer:
It is a scalene triangle.
Step-by-step explanation:
All the sides and angles are different/unequal.
