Answer:
i don't know where is the picture of the problem or are you missing parts of the problem?
Step-by-step explanation:
Answer:
( 8 , - 8) => x² - 55 = 9
( 4 , - 4) => 2x² - 32 = 0
(5 , - 5) => 4x² - 100 = 0
(11 , - 11) => x² - 140 = -19
( 3, - 3) => 2x² - 18 = 0
Step-by-step explanation:
1)

x = ( 4 , - 4)
2)

x = ( 5 , - 5 )
3)

x= ( 8 , - 8)
4)

x = ( 11 , -11)
5)

x = ( 3 , - 3)

Answer:
Tom's share = €800
Step-by-step explanation:
Given that:
Amount shared by Al, Tom and Joe = €3000
Ratio of Al's share to Tom's share = 5 : 4
Joe's share = 1.5(Tom's share) = 1.5(4) = 6
Therefore,
Ratio of Al, Tom and Joe = 5 : 4 : 6
Let,
x be the number of times of amount each get.
5x + 4x + 6x = 3000
15x = 3000
Dividing both sides by 15

Tom's share = 4x = 4(200) = €800
Hence,
Tom's share = €800
