Question

Using V = lwh , find an expression in factored form for the volume of this prism. Explain the general steps you used to arrive at this answer.

Answer 1

The student made a mistake in Line 1: AC=2, DF=2 AC ≅ DF .

Answer 2

Write 2x – 5 over 1.

Factor numerators and denominators, when possible

Divide out common factors to simplify.

Determine that the volume is (x)(6x)(2x – 5).
