La sumatoria de los ángulos internos de un polígono regular es 2700°, calcula: a) El número de lados. b) La medida de cada ángulo interno. c) La medida de cada ángulo externo. d) El número de diagonales.

When turned about its axis of rotation, which shape could have created this three-dimensional object?

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
