This can be put into a formula like so:
Since they are 6 consecutive even numbers, they will alternate odd/even/odd/even.
x, x+2, x+4, x+6, x+8, x+10 = 126
Simplify
6x + 30 = 126
6x = 96
x = 16
And you want the fourth number, so plug the x value back into the equation of 'x+6' and you will get 16+6 which = 22.
The LCD of 1/3 and 2/9....ur basically looking for the lowest number that both 3 and 9 go into evenly...and that number is 9
This question is open ended and doesn't have the necessary information.
hexa means 6, so I would assume 6x5 = 30 ft, but then you want to have a side open for a 'door', so subtracting 5 would make the answer 25ft.<span />
