Answer:
Step-by-step explanation:
Although you can start with 4x^2-2x-4=0, it's just slightly easier to reduce the coefficients. 4x^2-2x-4=0 becomes 2x^2 - x - 2 = 0.
The discriminant (part of the quadratic formula) is b^2 - 4ac. Using b = -1. a = 1 and c = -2, we get (-1)^2 - 4(2)(-2), or 17.
-b ± √(b^2 - 4ac)
Then the quadratic formula x = ---------------------------
2a
-(-1) ± √17 1 ± √17
takes on the values x = ----------------- = ---------------
4 4
2.3+3.1+1= 6.4
25÷6.4= 3.90625
3 tasks can be completed in 25 minutes.
The highest is 7 degrees and lowest is -8 so subtract and you get a difference of 15 degrees
140oz I believe because you just do 14oz times 10 because one dozen is 12 and 12 times 10 is 120.
