<span>(3k^2+2)(k+5^2)
so first simplify the 5^2 = 25
so </span><span>(3k^2+2)(k+25)
now open the brackets :
3k^3 + 75k^2 + 2k + 50
are you sure that the question has been copied exactly? as none of the options are correct in this case </span>

Answer:
The correct answer is diagonals are equal and bisect each other.
Step-by-step explanation:
A rectangle is a quadrilateral with opposites sides equal in length and all interior angles equal to 90°. Opposite sides are parallel and adjacent sides are perpendicular. Diagonals in a rectangle are equal in length and they bisect each other. If we want to draw a circumcircle, then the point of intersection of these diagonals give the circumcenter.
