20 ohm resistor in series with a 10 ohm resistor, each are 1/4 watt power, does that equal 5 watts of power?
the guy said its 5 watts of power
i doubt it
how much power does the two have together?

no .... it is a 30 ohms ---0.375 watt
max current for 10 ohm →0.158A
max current for 20 ohm →0.112 A
in series connection acceptable answer is 0.112A so for a 30 ohms → 0375 watt

SAME AS A 1/4 W 30 OHM RESISTOR.

If uses in series so the current through each is the same, the 20 Ohm resistor will be dissipating 250mW at around 112mA.
At that current, the 10 ohm resistor will only be dissipating 125mW
The that's the maximum possible power without exceeding the resistor ratings:
