Answer:
lower price = 3
higher price =11
Step-by-step explanation:
p(x) = -2(x-3) (x-11)
Setting equal to zero
0 = -2(x-3) (x-11)
Using the zero product property
x-3 = 0 x-11 =0
x=3 x = 11
Answer:
1.93433
Step-by-step explanation:
Since all triangles have an interior angle sum of 180, the second angle is 45. this also means that x and y are equal. Using the pythagorean theorem, we can produce the equation 
. dividing both sides by two we get 
. when we take the square root of root 14 we get 1.934335
It's 15 because
3 groups and 5 people in each group
and becomes 15

Answer:
x = 8/9
Step-by-step explanation:
6(3x - 4) = -8
Distribute the 6
18x -24 = -8
Add 24 to each side
18x -24+24 = -8+24
18x = 16
Divide each side by 18
18x/18 =16/18
Simplify the fraction by dividing top and bottom by 2
x = 8/9
