1. a rectangle has an area given by a=x^2+5x+6. find expressions for the possible lengths and width of the rectangle. 2. the profits of a company are found by subtracting the company's costs from it's revenue. if a company's cost can be modeled by 14x+120,000 and it's revenue can be modeled by 40x-0.000x^2, what is the expression for the profit?

1.  , which implies that the sides could be and .  (There are theoretically an infinite number of side-lengths, though--in general, for any polynomial or reciprocal of a polynomial , and is valid.  However, the set provided makes the most sense.)

2.  Profit is the difference between cost and revenue.  For revenue, , so revenue equals , so profit equals

4038 is the answer lol just use a calculator
