The answer should be x=4/3
9514 1404 393
Explanation:
The quadrilateral will be a parallelogram if the diagonals bisect each other. That will be the case if the sums of their end-point coordinates are the same.
A + C = (-3, 6) +(9, -9) = (6, -3)
B + D = (6, 0) +(0, -3) = (6, -3)
Both diagonals have their midpoint at (3, -1.5), so the diagonals are mutual bisectors. The figure ABCD must be a parallelogram.
___
The midpoint of AC is (A+C)/2 = (6, -3)/2 = (3, -1.5).
Length of the arc = 1/2 πD = 1/2 x 3.14 x 6 = 9.42 yd
Perimeter = 9.42 + 6 + 6 + 6 = 27.42 yd

Answer: 27.42 yd

Answer:
day 14 , 450 dollars
Step-by-step explanation:
We called x is the number of days
Zippy Rent-a-car: 25x + 100
Speedy Rent-a-car: 30x + 30
25x + 100 = 30x + 30
25x -30x = 30 - 100
-5x = -70
x = 14
