A) To factor a quadratic equation, standard form is the better form to use because it is easier to pull out a common factor from.
b) To graph a parabola, it is better to use vertex form so that you will know what point to graph as the vertex of the parabola.
c) To identify the vertex, maximum and minimum, it is better to use vertex form because the vertex form will give the values of the coordinates for the vertex. Then, you can use the equation to find the mininmum or maximum. If the graph is negative, it will have a maximum because it points downward infinitely. If the equation is positive, the graph will have a minimum because the graph points upward infinitely.
d) Standard form is easier to use when trying to solve using the quadratic formula because it is easier to see what the coeffiecnts and constants are to plug in for a b and c.
Answer:
Trees.

Answer:
Area of the shaded region= 
Step-by-step explanation:
Area of the shaded region= Area of the triangle- Area of the rectangle
Dimensions of the triangle:
Base= 40 inch
Height= 40 inch
Area of a triangle=
Area of the rectangle= Length*Width
Length=30 inch
Width=10 inch
Area:
Area of the shaded region=
