Let the numbers be x and y x+y=10…(1) x=10-y…(2) xy=24….(3) Put eqn (2) in eqn (3) (10-y)y=24 10y-y^2=24 y^2-10y-24=0 The coefficient of y multiply by twenty four y^2-6y-4y+24=0 y(y-6)-4(y-6)=0 (y-4) (y-6) y=4 or6

Problem 1: A man (the system) walks inside an isolated room for 5 hours and does W=1250JW = 1250 , text{J}W=1250J of work. The internal energy decreases by U=2250JDelta U = -2250 , text{J}U=2250J. Determine the heat QQQ (with sign). Follow-up: If the system instead gains 3000J3000 , text{J}3000J of heat while performing the same…
