Answer:
We can rewrite this expression like this:
And we can use the quadratic formula given by:
Where
And replacing we got:
And solving we got:
And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75
Step-by-step explanation:
For this case we know that we have a rectangular playground and the area can be founded with this formula:
Where x represent the width and y the length. From the problem we know that A =1400 m^2 and the heigth is 10m longer than the wide so we can write this condition as:
And replacing this formula into the area we got:
We can rewrite this expression like this:
And we can use the quadratic formula given by:

Answer:
P(x) = 58x - 8,500
Step-by-step explanation:
The profit function can be modeled based on the two given points of format (P, x) that are ($1360, 170) and ($4260, 220). The slope of the function is:
Applying the general form of a linear equation, the profit function is:
The profit as a function of units sold is P(x) = 58x - 8,500.
