1 board that is 10 feet long and make that into 6 table legs. Take the amount we have over the amount we want, so 10 over 6 which is 1.6666667 feet which is the longest each leg can be for a 10-foot board.
This is the first half of the question.
Let's solve your equation step-by-step.5x=9x3+2x2−5x+4Step 1: Subtract 9x^3+2x^2-5x+4 from both sides.5x−(9x3+2x2−5x+4)=9x3+2x2−5x+4−(9x3+2x2−5x+4)−9x3−2x2+10x−4=0Step 2: Use cubic formula.x=−1.31953Answer:<span>x=<span>−1.31953
