Let's recall the formula for getting the area of a square:
[tex]\text{ Area = s}^2[/tex]Given,
s = x - 5
To get the expression that best represents the area of the square, let's substitute the value of s in the formula.
[tex]\text{ Area = s}^2[/tex][tex]\text{ Area = (x}-5)^2\text{ = (x - 5)(x - 5)}[/tex][tex]\text{ Area = x}^2-5x-5x+25=x^2\text{ - 10x + 2}5[/tex]Therefore, the answer is letter D.
