(2n+3)²-(2n+1)²=(4n²+12n+9)-(4n²+4n+1)=8n+8= 8(n+1)Hence a multiple of 8

2n+1 will always be an odd number (e.g. if n is equal to 3 the answer would be 7, an odd number) So, we square 2n+1 and write this as (2n+1)² 2n +12n 4n...

Tectonic hazards are hazard events that occur as a result of tectonic activity. There are two forms of destructive plate margins: subductive and collision. A collision plate margin occurs when two contine...

Diffusion is the movement of a substance from areas of high concentration to areas of low concentration, down a concentration gradient. As a result of diffusion, substances may move in and out of cells, a...
