Y 50 I think it is I am not to sure
4:5 because a quadrilateral has 4 sides and a pentagon has 5 sides
V=(1/3)(area of the base)(<span>altitude)
V=</span><span>(1/3)(</span>6²)(6)= 72 m³
= 3x(2x^2 - 4x - 5) - 6(2x^2 - 4x - 5)
= 6x^3 - 12x^2 - 15x - 12x^2 + 24x + 30
= 6x^3 - 24x^2 + 9x + 30 (answer)
