Best ResponseYou've already chosen the best response.0So why did it only cancel out the 4 and not the 2. was it to only find half of from only one part (or one number).

Best ResponseYou've already chosen the best response.0it is half base times height OR half height times base half height = 4z/2 = 2z

Best ResponseYou've already chosen the best response.1it works the same as \[ \frac{1}{2} \cdot 4 \cdot 8 \] you can group it like this \[ \left(\frac{1}{2} \cdot 4 \right) \cdot 8\] only the 4 *1/2 is simplified to 2 and you get 2*8 or 16 if 8 were something complicated like (x+2y) it still be \[ \left(\frac{1}{2} \cdot 4 \right) \cdot (x+2y)\]

Best ResponseYou've already chosen the best response.1we know that 2+1 = 3 nd if we find out (2+1)/2 then we can't cancel out 2 :) if u cancell it out then ur left with 1 but we know that 2+1 = 3 nd 3/2 is not 1. so u can't divide like that
