Answer:
This is the transitive property of equality says that if a = b, and b = c, then a = c
To solve (8/5 + 4)7, you first have to add 8/5+4. But you cannot simply add the too because they have to be in a common denominator 'form'. To do that, we find a common denominator which is 5. We then multiply 4/1 by 5.
8/5 + 4/1= 8/5 +20/5.
Now you can solve; 8+20= 28. You leave the denominator as 5.
You get 28/5 and now you have to multiply it by 7/1. Another of saying 28/5 is 5 3/5. So 5 3/5 x 7/1= 39 2/10 (final answer)

In order for a regular polygon to tile a plane, the interior angle must be a divisor of 360°. The interior angle at each vertex will have measure 180(n -2)/n for an n-sided polygon. So you must have
.. 360/(180(n -2)/n) is an integer
.. = 360n/(180(n -2))
.. = 2 +4/(n -2)
That is, n-2 must be a divisor of 4, one of 1, 2, 4. So, the number of sides of the regular polygon must be 3, 4, 6.
Of your choices, A and D are appropriate.
