Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
