All of them but B because a polygon only needs 3 or more sides when B isn't really a figure.
The answer to the question is B.
Answer:
p = 3, q = 2.5
Step-by-step explanation:
Given that x = - 4 is a root of the equation, then
(- 4)² - 4p - 4 = 0, that is
16 - 4p - 4 = 0
12 - 4p = 0 ( subtract 12 from both sides )
- 4p = - 12 ( divide both sides by - 4 )
p = 3
Also given that the equation x² + px + q = 0 has equal roots
Thus the value of the discriminant b² - 4ac = 0
Here a = 1, b = p and c = q, thus
p² - 4q = 0 ← substitute p = 3 from above into the equation
9 - 4q = 0 ( subtract 9 from both sides )
- 4q = - 9 ( divide both sides by - 4 )
q = 2.5
Answer:
120 gallons would be needed
Step-by-step explanation:
You multiply both gallon amounts by the amount of people which is 60 to find how much water would be needed and you subtract them to find the difference.
(60x8)-(60x6)=
480-360= 120
