What is an expression equivalent to
4b + 5y - 3b + 8y

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 %

Ineed to know the ordered pairs for this equation i need the answer quick because it’s a timed test

5divided by 6.55? can i have the complete answer like in the model
