Alan wants to make a metal cylinder (with length of 40 MM) melt down a solid metal sphere with a volume 36000mm^3 Once the cylinder is made it is painted with a protective coating. Calculate total surface area needed to be covered.

Simplify 15(x - 4)(x -1)-3(x + 4)(x - 1) with steps

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3

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
