3 2/3 = 1/2 an hour

3 2/3 x 2 = 1 hour

3 2/3 = 11/3

11/3 x 2 = 22/3

22/3 = 7 1/3

Another way is:

3 2/3 + 3 2/3

3 + 3 = 6

2/3 + 2/3 = 4/3 = 1 1/3

6 + 1 1/3 = 7 1/3

Which of the expressions below can be factored using the difference of squares method? A. 25x2 - 64y2 B. 17x2 + 23y2 C. 17x2 - 2

<span>Difference of squares method is a method that is used to evaluate the difference between two perfect squares.

For example, given an algebraic expression in the form:
$x^2-y^2$
can be factored as follows:
$(x-y)(x+y)$

From the given expressions, the only expression containing two perfect squares with the minus sign in the middle is the expression in option A.
i.e. $25x^2-64y^2$
which can be factored as follows:
$(5x-8y)(5x+8y)$ .</span>
