20a + 45 = 5(4a + 9)
-4(5a-3) = -20a + 12
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
12

No, it is not safe to replace a 125V 20A fuse with a 220V 20A fuse. Fuses are designed to protect electrical circuits from overloading, and using a higher voltage fuse could lead to damage or fire hazards in the circuit. Always replace a fuse with the same voltage and amperage rating as the original.
F9 and its a 20A fuse :)
