We first expand the first set of brackets by multiplying each element of it by the second set of brackets so (x + 1)(2x + 3) = (x)(2x + 3) + (1)(2x + 3) = x(2x + 3) + (2x + 3). We can then expand out the ...

x=4, y=-2

Firstly, a description of water potential would be a good place to start. An example definition of this could be: the pressure created by water molecules. The greater the number of water molecules present...

Rewrite as arg(z-5) - arg(z-3) = π/6 and let arg(z-5) = b and arg(z-3) = a, so that b-a = π/6Since we know that each argument makes a half line (starting at (3,0) for angle a, (5,0) for angle b) the half ...

"Photo" means light and "synthesis" means to make something. Photosynthesis is the production of oxygen and glucose from sunlight, carbon dioxide and water in green plants. The glucose...
