For 1995 through 2005, the number n (in thousands) of units produced by a manufacturing company can be modeled by n = 1.4t + 2.1 and the profit p (in dollars per unit) can be modeled by p = 1.4t - 2.1 where t is the number of years since 1995.
a. write and simplify a polynomial that models the company total profits t (in thousands of dollars) in terms of the number of years since 1995.
b. what was the company's total profit in 2002?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
