Which polynomial represents the sum below? (x2 + 2x + 2) + (-2x6 - 3x5 - x2 + 6x) a. 2x6 + 3x5 - x2 + 4x - 2 b. -2x6 - 3x5 - 4x + 2 c. -2x6 - 3x5 + 8x + 2 d. -3x6 - 3x5 + x2 - 4x

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
