Four students (Students A, B, C, and D) each draw a triangle and measure its perimeter. The following table shows the perimeters reported by the four students. If all sides of the triangles have whole number lengths, which student made a mistake in their perimeter measurement?

What point is the projection of q on a) r b) s c) t

If 3x+8=3x+8 is it one solution or no solution

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
