Question is in the photo, thank you for helping.

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 %

Mis the midpoint of rq if rm equals 2x + 5 and mq equals 4x - 9 what is the length of rq

What is the remainder when 3x^2-x-10 is divided by x-1 -6,-7,-8, or -9
