Question

The square below has an area of x^2- 10+ 25 square meters. What expression represents the length of one side of the square?​

Answer 1

9514 1404 393

Answer:

 (x -5) meters

Step-by-step explanation:

We assume the area is supposed to be ...

  A = s^2 = x^2 -10x +25

This is a perfect square trinomial, so can be factored as ...

  A = s^2 = (x -5)^2

Then the side length can be represented by the expression ...

  s = (x -5) . . . . meters
