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:
Answer:
He has $36 Left
Step-by-step explanation:
Multiply 5/8 and 120
75 (Money spent)
120 - 75 = 45
45 (Money Left)
Multiply 1/5 and 45
9 (Money Spent)
45 -9= 36
He has $36 Left

Answer:
$4
Step-by-step explanation:
Because we know that Nancy bought a drink for 2 dollars, and we are just trying to find the cost of the candy bars, we can subtract 2 dollars from the drink from the total cost:
38 - 2 = 36
Now, the 9 candy bars cost 36 dollars, so to find the individual price of each candy bar, we divide 36 by 9:
36 / 9 = 4
So, each candy bar costs 4 dollars
Hope this helps :)
