An artist built a wooden sculpture in the shape shown below. Which expressions could be used to find the volume of the sculpture? Select all that apply. (7 × 8 × 2) + (7 × 7 × 4) (8 × 2 × 7) + (9 × 4 × 7) (2 × 4 × 7) + (7 × 4 × 7) (9 × 4 × 7) + (2 × 7 × 4) (2 × 7 × 7) + (7 × 6 × 4)

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
