Solve the incomplete quadratic equation:

$\mathsf{3m^2-24m=0}\\\\ \mathsf{3m\cdot m-3m\cdot 8=0}\\\\ \mathsf{3m\cdot (m-8)=0}\\\\ \begin{array}{rcl} \mathsf{3m=0}&~\textsf{ or }~&\mathsf{m-8=0}\\\\ \mathsf{m=0}&~\textsf{ or }~&\mathsf{m=8} \end{array}$

Solution set: S = {0, 8}.

I hope this helps. =)

Lashonda is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.C

musickatia [10]

Answer:
30 < m
The solution would be (30, ∞)

Explanation:
For company A:
The charge is: $96 for any number of mileage ..............> I
For company B:
The charge is $75 fixed and 0.7 for each mileage m. This means that the charge is: 75 + 0.7m .................> II

We want the charge of company A to be less than the charge of company B. This means that we want I to be less than II.
Therefore,
96 < 75 + 0.7m
96 - 75 < 0.7m
21 < 0.7m
21/0.7 < m
30 < m

This means that for any mileage greater than 30, the charge of company A will be less than the charge of company B

Hope this helps :)
