Numbers are x, x + 2 and x + 4. then x + 2(x + 2) + 3(x + 4) = 82 ie x + 2x + 4 + 3x + 12 = 82 ie 6x = 82 - 4 - 12 = 66 therefore x =11 and the other numbers are 13 and 15. Check: 11 + (2 x 13) + (3 x 15) = 11 + 26 + 45 = 82 QED
x2 - 83x + 82 = x2 - 82x - x + 82 = x(x-82)-1(x-82) = (x-1)*(x-82)
12 x 6' = 72" 72" + 10" = 82" 82" x 2.54 = 208.28cm
82/3 x 12 = 26/3 x 12 = 26 x 4 = 104
82 = 1 x 82, 2 x 41, 41 x 2, 82 x 1.
1 x 82, 2 x 41 = 82
738. 10 x 82 = 820, so 9 x 82 is 820 minus 82 (It is 82 less than 10 x 82)
1' = 12" 6 x 12 = 72 So 6'10" = 72+10 = 82"
6x12=72 6x10=60 6x2=12 60+12=72
82 x 67 = 5494
82 x 2 = 164
