72 = 6 x 12 = 8 x 9 = 9 x 8
(8 - x) / 6 = 98 - x = 54x = 8 - 54x = -46OR8 - (x/6) = 98 = x/6 + 9x/6 = 8 - 9 = 1x = 6
If x = 8, then 23 -x - 9 = 23 - 8 - 9 = 6
(-6 x 8) + (6 x 9) = 6 is one solution. 6-8 / 6-9 is another solution.
(x + 8)(x + 9)
9 x 8! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1So, 9 x 8! = 9! = 362,800
9 x 8 - 64 = 8
No, 96 = 12 x 8...
(2 x 3 x 4 x 5 x 6 x 7 x 8 x 9) + 1 will have a remainder of 1 when divided by 2, 3, 4, 5, 6, 7, 8, or 9. (2 x 3 x 4 x 5 x 6 x 7 x 8 x 9) + 1 = 362,881
The answer is '72'. However, learn your '8' times table and your '9' times table. of multipolication. 8 times 8 x 1 = 8 8 x 2 = 16 8 x 3 = 24 8 x 4 = 32 8 x 5 = 40 8 x 6 = 48 8 x 7 = 56 8 x 8 = 64 ( 8^2 ; 8 squared) 8 x 9 = 72 ( as answered) 8 x 10 = 80 8 x 11 - 88 8 x 12 = 96 And 9 times 9 x 1 = 9 9 x 2 = 18 9 x 3 = 27 9 x 4 = 36 9 x 5 = 45 9x 6 = 54 9 x 7 = 63 9 x 8 = 72 ( as answered) 9 x 9 = 81 ( 9^2 ; 9 squared) 9 x 10 = 90 9 x 11 = 99 9 x 12 = 108
3 x 3 = 9 2 x 2 x 2 = 8 2 x 7 = 14 2 x 3 = 6
