Abox 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? a) y = 5(28 – x)(x)b) y = 5(28 – 2x)(x)c) y = 5(14 – x)(x)d) y = 5(14 – 2x)(x)

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

2: 10

step-by-step explanation:

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
