Find the length of the missing side of the perimeter is 30ft

Solve the equation by completing the square. x^2+2x=17

Which function has the domain x> -11? y= x+ 11 +5 y= x-11 +5 y= x+5 - 11 y= x+5 + 11

Kite abcd is rotated 180 degrees clockwise about the origin and then reflected over the y-axis, followed by a reflection over the x-axis. what is the location of point a after the transformations are complete?
