No 2x10=20 and 2x11=22. They are not equal
80
This formula can be better expressed as [(1+2)(2+3)(3+4)] = (20+x)/2. Simplifying, we get 2[(3)(5)(12)] = 20+x. Then the equation becomes 2[180] = 20+x, or 360 = 20+x. Transferring 20 to the other side, we get 360-20 = x. So, x = 340.
it means that x should equal 10. x + x = 20. x = 10
1, 2, 4, 5, 8, 10, 20, 40: 1 x 40, 2 x 20, 4 x 10, 5 x 8Also, 2 x 2 x 2 x 5 = 40
