The vertices of a triangle have the coordinates A(3,4), B(-2,-1), and C(-7,6). Determine if it is a right triangle? Justify your response.(somebody please answer quick)

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

The center of the circumscribed circle lies on line segment and the longest side of the triangle is equal to the of the circle.
