The length of each arch segment is 6ft.
<h3>What is a quadratic equation?</h3>
Quadratic equation is an algebraic equation with the highest power of its variable as 2.
Analysis:
The points at which the curve touches the floor, f(x) = 0
so, - +2x + 8 = 0
- +4x -2x +8 = 0
-x(x-4) -2(x-4) = 0
(-x-2)(x-4) = 0
x = -2 or 4
so length of segment along the floor of each arm, the distance from -2 to 4 on a graph is 6 = 4--2 = 6 feet
In conclusion, the length of the segment along the floor of each arch is 6 feet

Answer:
David: $8,000
Jen: $14,000
Step-by-step explanation:
The amount that Jen owes = j
The amount that David owes = d
Jen and David owe $22,000 in loans for their two cars, then
The amount of the loan for Jen’s car is $2,000 less than twice the amount of the loan for David’s car, then
- twice the amount of the loan for David’s car = 2d
- $2,000 less than twice the amount of the loan for David’s car = 2d - 2,000
then
Solve the system of two equations:
Substitute the second equation into the first:
Answer:
base times height divided by two. Answer is 144 ft
The answer is C. This is because the area of a triangle is height • (base divided by 2), which means the triangle has an area of 8 and the square in answer 3 has an area of 16. 8 is half of 16.
