Answer:

The lateral area of the prism is $84\ cm^{2}$

Step-by-step explanation:

we know that

The lateral area of the regular prism is equal to

$LA=Ph$

where

P is the perimeter of the base of the prism

h is the height of the prism

Find the perimeter of the base

$P=6(3.5)=21\ cm$ ----> is a regular hexagon (6 equal sides)

we have

$h=4\ cm$

substitute

$LA=(21)(4)=84\ cm^{2}$

Let's begin by listing out the information given to us:

A cubic function has the general form of:

$\begin{gathered} \displaystyle f(x)=ax^3+bx^2+cx+d \\ f(x)=y \\ y=ax^3+bx^2+cx+d \end{gathered}$

The function has real coefficients

Its zeros are 0, 1 & -4
