7.5 meters
One way to do the problem is to note that there is a dilation (scale) factor of 5 on the shadows, so there must be that factor on the heights too. Another way is to note that the shadows are twice as long as the heights.
$1.41
2016 = $42.20
2017 = $43.57
2018 = $44.98
44.98 - 43.57
=1.41
54
Hope this helps
a) x^2 + 3x = x(x+3)
b) 2x^2 - 8x = 2x(x - 4)
c) 6x + 9x^3 = 3x(2 + 3x^2)
d) 12x^3 - 4x^2 = 4x^2(3x - 1)
i think b
could be wrong sorry
