Brown-Red-Green-Gold yields what resistance?

Explanation:
This uses the standard four-band resistor code: two digits, a multiplier, and a tolerance. The first two bands give the digits 1 and 2, so that forms 12. The third band, green, is the multiplier and represents 10^5. Multiplying gives 12 × 100,000 = 1,200,000 ohms, which is 1.2 megohms. The final gold band indicates a tolerance of ±5%. So the resistor value is 1.2 MΩ ±5%.
