Question 168569: Hello,
I have solved this question and compared to another student, and we had different answeres. I've done it again, and got the same answer as before. Could you please confirm that it is correct, or help me solve it corectly? Thank you in advance.
[(12x^3)/5)] / [(4x^2)/(10(y+3)]
= [(12x^3)/5y] x [(10(y+3))/(4x^2)]
= [(12x^3)/5y] x [(10y+30)/(4x^2)]
= [3x(10y+30)] / 5y
= [(30xy+90x)] / 5y
= [(6xy+18x)] / y

Question 168341: Demand for pools. Tropical Pools sells an aboveground
model for p dollars each. The monthly revenue for this
model is given by the formula
R(p)= -0.08p2 + 300p.
Revenue is the product of the price p and the demand
(quantity sold).
a) Factor out the price on the right-hand side of the
formula.
b) Write a formula D(p) for the monthly demand.
c) Find D(3000).
d) Use the accompanying graph to estimate the price at
which the revenue is maximized. Approximately how
many pools will be sold monthly at this price?: Demand for pools. Tropical Pools sells an aboveground

Question 167953: Winter wheat. While finding the amount of seed needed to plant his three square wheat fields, Hank observed that the side of one field was 1 kilometer longer than the side of the smallest field and that the side of the largest field was 3 kilometers longer than the side of the smallest field. If the total area of the three fields is 38 square kilometers, then what is the area of each field?
