You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 2 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 2.
Number of blocks=1,450 feet * (1 block/2 feet)
Number of blocks = 725 blocks
Therefore, you would use a model requiring 725 blocks. The scale factor for the model is 1 block per two feet.

Commutative property of addition: The order in which you add these fractions together doesn't matter.
I would combine 3/5 and 2/5 first, as that readily results in 5/5, or just 1.
Then we have 1 1/4, or 1.25, or 5/4 as the final answer.
The answer for this problem is x=-2 or x=3.
<em>To solve, start with the equation.</em>
0=x^2−x−6
<em>Subtract x^2-x-6 from both sides.
</em>
0−(x^2−x−6)=x^2−x−6−(x^2−x−6)
−x^2+x+6=0
<em>Factor left side of equation.
</em>
(−x−2)(x−3)=0
<em>Set factors equal to 0.
</em>
−x−2=0 or x−3=0
x=−2 or x=3
