recall that the perimeter is simply the sum of all outer sides of a figure.

SEE ATTACHED IMAGE TO OBSERVE THE GRAPH OF THE FUNCTION.
For this case, the first thing we should see are the cut points with the x axis.
We note that the graph cuts to the x-axis at x = -2
Therefore, x = -2 is the real solution to the polynomial.
Also this function:
x3 + 6x2 + 12x + 8
It can be rewritten as:
(x + 2) ^ 3
From where we conclude that its roots are:
x = -2 (with multiplicity 3)
Answer:
the equation x3 + 6x2 + 12x + 8 = 0 have:
x = -2
As a real solution with multiplicity 3.
Area is squared so divide 56/6 gives you 9.3 round down so length of base is 9 m.
so if you do 9 divided by 60 and it will give you 0.15 and that is your answer
Y = kx
80 = 16k
k = 80/16 = 5
direct variation
