Answer:
The given fraction
reduces to 
Step-by-step explanation:
Consider the given fraction 
We have to reduce the fraction to the lowest terms.
Consider numerator 
We can take x² common from both the term,
Thus, numerator can be written as
Given expression can be rewritten as ,

We can now cancel
from both numerator and denominator,


Thus, the given fraction
reduces to 
No, because an equilateral triangle is also equiangular so all sides must be 60° (60+60+60=180) and an obtuse angle is more than 90° so the triangle would not be equilateral.

Answer:
See explanation
Step-by-step explanation:
One vertex is at point (2,3).
Go 1 unit to the left and 5 units up, then the second vertex will be at the point (1,8).
Go 5 units to the right and 1 unit up, then the third vertex will be at point (6,9).
Go 1 unit to the right and 5 units down, then the fourth vertex will be at point (7,4).
Go 5 units to the left and 1 unit down to get into the vertex (2,3).
Since you always move one unit in one direction and 5 units in another direction, obtained quadrilateral will be a square.
See attached diagram for details.
