We are learning how to find the volume of a prism. look at the picture and me understand it i need the answer

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.

Abcd is reflected across the x- axis, then rotated 90 clockwise about the orgin, and finally reflected across the line y= x to form a’ b’ c’ .

Felix wrote several equations and determined that only one of the equations has no solution. which of these equations has no solution?
