Question

Stephen purchases a square-shaped canvas to use for a painting. The diagonal of the square is 10 inches longer than the length of its sides. Stephen uses the Pythagorean theorem to create the equation x2 + x2 = (x + 10)2 to determine the side length, x, of the canvas. The side length of the canvas is best found by because the equation is . Solving the equation produces two measurements, and must be discarded for being unreasonable.

Answer 1

The side length of the canvas is best found by using the quadratic formula

because the equation is prime. Solving the equation produces two

approximate measurements, and one must be discarded for being

unreasonable.

I took the test and this was correct.
