I think the answer is
-14m^2 + 15m - 3
(The ^2 is squared)
Answer:
x = 60
Step-by-step explanation:
multiply 12 by 5 to get the numerator. 12/5 = 60.
to check, divide the numerator by the denominator.
Given mass=1 kg, volume=400cm³, density=?
The formula for finding density is ρ=m/v where ρ is density, m is volume and vis volume
ρ=1kg/400cm³
ρ=0.0025kg/cm³
Therefore the density of the sand is 0.0025kg/cm³
