When X=0, the function would be:
<span>f(x) = 4x^3 -20x2 + 24x
0= </span><span>4x^3 -20x2 + 24x ----->divide all by x
</span>x(4x^2 -20x + 24) =0 ------> split -20x into -12x and -8x
x(4x^2 -12x -8x + 24)
x{4x(x-3) - 8(x -3}
x(4x-8) (x-3)
x1= 0
x2= 8/4= 2
x3= 3
Area formula of a parallelogram is
A = base x height
Given are the
Area = 60 m² and base = 10 m
Substitute the given:
60 = 10h (divide by 10 to find value of h)

(10 and 10 cancels out)
h = 6The
height of a parallelogram with a base of 10m and an area of 60m² is
6m
