When multiplying two binomials, you must multiply each term in the first binomial by each term in the second binomial. Then you add each of the products together to evaluate the expression. You can visualize this series of multiplication and addition with this formula: (x + y) (a + b) = xa + xb + ya + yb. This is known as the distributive property of multiplication over addition.

Which of these correctly evaluates the expression (c + d) (e + f) ?

A. ce + cf + de + df

B. cd + ef + cd + ef

C. cd x ef

D. cd^2 + ce + ef

Recall that to find the cost to produce the nth unit in a production process, we calculate the difference C (n) - C (n-1) where C (n) is the cost of producing n units. The total cost (in dollars) for a fast food franchise of producing x thousand hamburgers might be C (x) = 18000+700x-80x2. Find the exact cost of producing the 2,001st burger. Be careful though. The units for x are thousand of hamburgers. The 2,001st burger is represented by 2.001!
