Hello help me please please pretty please

Find the sum of the measure of the interior angles of a polygon of 9 sides ; of 32 sides

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2

Solve the system of equations using the linear combination method. {4x−3y=127x−3y=3 enter your answers in the boxes.
