Answer:
k > 12
Step-by-step explanation:
If a quadratic equation has no real roots the values of b^2 - 4ac
( for the general form ax^2 + bx + c = 0) is negative,
So we have the inequality:
(-12)^2 - 4*3* k < 0
144 - 12k < 0
12k > 144
k > 12
So, x=7/3, -1.
5=3x-2
x=7/3
Here change 5 to -5.
5= 3x-2
x=-1
M = mass
p = density
v = volume
Yes, to find m it would be m = pv.
To find v that would be m/p.
