A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm, which quadratic equation best models the volume of the box? V = lwh P = 2(l + w) y = 5(28 – x)(x) y = 5(28 – 2x)(x) y = 5(14 – x)(x) y = 5(14 – 2x)(x)

Respuesta :

mathmate
perimeter = 2(width+length) =28
Let x=width of base, then length of base = (28/2)-x = 14-x
Volume of box = length*width*height
=x(14-x)*5 = 5x(14-x)

Answer:

y = 5(14 - x)(x)
