and 
bisect each other (given)
2) 
is a parallelogram (a quadrilateral with diagonals that bisect each other is a parallelogram)
3) is a rhombus (a parallelgoram with congruent diagonals is a rhombus)
4) 
(halves of congruent segments are congruent)
I know this is late but the greatest common factor between the two is 2a.
Answer:
The number of skateboard company sell during the month of August = 55
Step-by-step explanation:
We have given,
Profit function for Bob, P = x²+ 10x - 12
Bob's profit during August month is $3,563
That means, P = $3,563
We can use the profit formula given for Bob's profit:
P = x² + 10x - 12
Plug P =$3,563 in above formula.
i.e 3,563 = x² + 10x - 12
or 0 = x² + 10x -12 - 3,563
or 0 = x² + 10x - 3575
or x = 55, -65
Since number of skate boards can not be negative.
So we consider x= 55
Hence the number of skateboard company sell during the month of August = 55.
Answer:
$404.40
Step-by-step explanation:
18 / 2 = 9ft (Radius)
A = pi(9^2)
