Answer: Option A. N
Solution
The three given sides form a triangle with sides 720, 756, and 1,044
The largest side is 1,044. We can use the Pythagoras Theorem to clasify the triangle comparing the square of the largest side with the sum of the square of the other two sides:
1,044^2 compared with 720^2+756^2
1,089,936 compared with 518,400+571,536
1,089,936 compared with 1,089,936
1,089,936 = 1,089,936
Beacuse of we get an equality, this is a right triangle and the angle between the smallest sides must be right: the angle between 720 and 756 must be 90°. These sides must be perpendiculars, and because of the side of 720 is horizontal (east), the side of 756 must be vertical (north).
Technically, all of the choices can be written as a difference of squares. Just find the square root of both terms and use the formula
where and are terms.
However, I am going to assume that your problems want to know if the expressions can be written as a difference of two squares, where and are either variables with an even exponent or a perfect square, as this is what many instructors are asking for.
A) A cannot be written as a difference of two squares, because even though 25 is a square, is not a variable with an even exponent, which means that we can not apply the Differences of Squares.
B) Similar to Choice A, we cannot apply the Differences of Squares given the context because 18 is not a perfect square.
C) We can apply it to Choice C, since has an even exponent and 36 is a perfect square. Applying the formula, we get:
