(x+y)^2=56
x^2+2xy+y^2=56. we know that xy=12
so 2(xy)=24
x^2+24+y^2=56
x^2+y^2=56-24
x^2+y^2=32. <-------------
Hm.... I don't know. Is he an actor or some sort of performer?
Answer:
the 2000 represents the base salary he makes
Explanation:
we know that the salesman makes money from two things the base salary and the commission he takes on his sales.
it is clear that the base salary he takes is a fixed number while the commission varies with the sales he makes.
in this equation the number 2000 is fixed so it is the base salary (it does not change with the sales he makes).
but the 0.1s changes when s, total sales, changes so it is the commission he makes.
hope that was helpful.
