Question

The density of a substance equals its mass divided by its volume. The mass and volume of a certainchemical substance are changing according to the functions below. Which expression describes thedensity, M(t) - V(t)?M(t) = 6t? + 15t - 4. where t = time in minutes and M(t) = mass in gramsV(t) = 3t+ 3, where t = time in minutes and V(t) = volume in cubic centimeters2t + 3 - 133+32t + 3+ 53+3ОАО В2 + 7-22+ + 7+3+3

Answer 1

`\begin{gathered} M(t)=6t^2+15t-4 \\ V(t)=3t+3 \\ So, \end{gathered}`
`\begin{gathered} So,\text{ the answer is} \\ 2t+3-(13)/(3t+3) \end{gathered}`
