What is the value of the expression x-y squared when x equals 7 and y equals negative 2?
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.

How would you write the algebraic expression for one fourth the difference of a number and 7?
The algebraic expression for one fourth the difference of a number and 7 can be written as (1/4)(x - 7), where x represents the unknown number. This expression first calculates the difference between the number and 7 by subtracting 7 from the number (x - 7), then finds one fourth of that difference by multiplying the result by 1/4.
