Answer:
40
Step-by-step explanation:
b² - 4ac
= 16 - 4(3)(-2)
= 16 + 24
= 40
2x + 7y + 3x + 5y
5x + 12y
Answer:

I hope this helps
Step-by-step explanation:
Mean is the average
So the first mean is 11
The second one is 14.7 so round to 15
15-11 is 4. Hope that is correct
By definition we have that the volume is given by
V = h * w * l
where
V: Volume
h: height
w: width
l: length
Clearing the height we have:
h = V / (w * l)
h = (5 - x) / ((x) * (x - 2))
The expression is not defined for the values of x that make the denominator zero:
((x) * (x - 2)) = 0
x = 0
x = 2
Answer
h = (5 - x) / ((x) * (x - 2))
x = 0
x = 2
