How do u find the circumfrance and area of a circle by only knowing the radius?

Measures of the angle of r, 31 s (x+4) t (3x+9)

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

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
