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:
C) 2400
Step-by-step explanation:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
Computers = 10
Printers = 3
Scanners = 5
Telephone = 8
Copiers = 2
Possible outcome = 10 x 3 x 5 x 8 x 2 = 2400
This equation is equal to 5*4 so it equals 20
