An expression which is represented by the diagram (see attachment) is: A. -6 - (-1).
<h3>What is an expression?</h3>
An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
By critically observing the diagram (see attachment), we can logically deduce the following information:
- There are a total of 6 negative tiles.
- Among the 6 negative tiles, 1 tile is crossed out.
In this context, we can the diagram (see attachment) by using the following expression:
-6 - (-1)

Answer:
Step-by-step explanation:
The given expression is
There's a exponent which relates fractional exponents and roots, that is
So, if we apply this property, the results would be
Therefore, the right answer is the third choice
1 year has 365.25 days in it (that's why we add a leap day every 4 years)
1day=24hours
1hour=60mins
1min=60secs
365.25*24*60*60=31557600 seconds in a year
2.05*10^5=205000 seconds
205000/31557600=0.0064905800187593479859051385403 years
Perimeter = Sum of three sides.
Let the third side be = t
Perimeter = 8x + 3y
8x + 3y = (4x + y) + (2x - 3y) + t
8x + 3y = 4x + y + 2x - 3y + t
8x + 3y = 4x +2x + y - 3y + t
8x + 3y = 6x - 2y + t
8x - 6x + 3y + 2y = t
2x + 5y = t.
Therefore third side = 2x + 5y
