Here is a cuboid. Jackie tries to work out the volume of this cuboid.
Here is her working.

10 + 20 + 5 = 35cm

She has made two errors. What are her errors?

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

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
