Little Tommy built a train out of LEGOS. One-sixth of the train was made with blue blocks, 5/8 of the train was made with red blocks and the remaining five blocks were yellow.
How many LEGO blocks long was Tommy's train?

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
