Answer:
x = 3 and -2 are the two solutions.
Step-by-step explanation:
2x^2 -2x -12 = 0
First factor out a 2
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0
2 = 0 x - 3 = 0 x + 2 = 0
2 does not equal zero so this is an extraneous solution
x - 3 = 0 so x = 3
x + 2 = 0 so x = -2
1.5 cups = 0.09375 gallon
per week = 7 days
So, 0.09375(7) =0.65625 gallon /week
Or you could round it to 0.66
2csc^2x + 1 is the correct answer to simplify this expression
Answer: = (-8,-4)(-6,-1)=54
Step-by-step explanation:
Answer:
The substance will not be in liquid state in range -273.15
(absolute zero) to -47.42
and the temperature above 364.76
Explanation:
The Substance will be in solid state in at the temperature below its melting point and it will be is gaseous state at the temperature above its boiling point. So it will be liquid between melting and boiling point.
