Answer: a = 4
Step-by-step explanation: Area of a triangle is calculated as: 
.
The triangle formed by the parabola has base (b) equal to the distance between the points where the graph touches x-axis and height (h) is the point where graph touches the y-axis.
The points on the x-axis are the roots of the quadratic equation:
a(x-3)(x+2)=0
(x-3)(x+2)=0
x - 3 = 0
x = 3
or
x + 2 = 0
x = -2
So, base is the distance between (-2,0) and (3,0).
Since they are in the same coordinate, distance will be:
b = 3 - (-2)
b = 5
Area of the triangle is 10. So constant a is
5a = 10.2
a = 4
The constant a of the function y = a(x-3)(x+2) is 4.

Step-by-step explanation:
Answer:
Sunii will make 14 fewer montly payment payments with plan two.
Step-by-step explanation:
Plan one will take Sunii 24 months to pay off, we can know this by calculating by doing the formula, (total price= base payment/ monthy payment.) so in his case will have this.
Plan one: (750-150=600), then (600/25=24), so it will take Sunii 24 months to pay off his horse.
Plan two: (750-200=550), then (550/55=10), so it will take Sunii 10 months to pay off his horse.
Overall: The 24-10= 14 which would be the diffrence in time depending on th eplans.
Just look up a linear calculator.
