Some of the steps for completing the square to solve
x2 + 5x = 2 are shown.
x2 + 5x = 2
x2 + 5x + (startfraction 5 over 2 endfraction) squared = 2 + (startfraction 5 over 2 endfraction) squared
(x + startfraction 5 over 2 endfraction) squared = startfraction 33 over 4 endfraction
which are solutions of x2 + 5x = 2? check all that

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
