A rhetorical question is a question you ask someone, but you do not expect or need an answer. Often you know the answer to the question already. They are often used in emotive writing to emphasise particu...

(x+3)(x+2)=F=xx= x^2O=x2=2xI=3x=3xL= 3*2=6=x^2 + 2x + 3x + 6= x^2 + 5x + 6

3x+2y=8 (1)2x+5y=-2 (2)So you need to have a common multiple of either x or y in this example I’ll equate the x of both equations so I’ll multiply (1) by 2 and (2) by 3 2( 3x+2y=8). 6x+4y=16 (3).3(2x+5y=-...

Water molecules move down their concentration gradient, across the partially permeable cell membrane, from a high concentration to a low concentration. Osmosis continues until the concentration of water m...

Because metals contain a ‘sea’ of delocalised electrons that are free to move around the metallic lattice, carrying charge.
