Imagine writing Π9i = 6 i(i + 2) (i − 1) · (i + 1) in extended form. What factor corresponds to i = 6? What factor corresponds to i = 9? Π9i = 6 i(i + 2) (i − 1) · (i + 1) =

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
