Bath tub: 60 x 30 x 18
brick: 8 x 4 x 2
fermi process:
(60 x 30 x 18) / (8 x 4x 2)
= 32,400 / 64
= 506.25
estimated as 500 bricks
When talking about object measurements, we usually require they be positive.
A suitable domain is x > 0.
(and somewhat less than any substantial fraction of the Earth's dimensions. The numerical value will depend on the chosen units.)
2 2/3 I think. Hope I helped!
here's the solution,
first term (a) = -5x
common difference (d) = (8x + 4) - (-5x - 1)
= 13x + 5
now, we know,
