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
1 x 20 2 x 10 4 x 5
There are infinitely many quadratics that can equal 20.For example, given any positive number, a, a*x^2 + 20 will equal 20 for x= 0.
I assume you mean (x+10)(x+2) This would equal x^2+12x+20 x^2 means x squared
20% of 2 equates to 2 x 20/100 = 40/100 = 0.4
1 x -20 or -1 x 20 2 x -10 or -2 x 10 4 x -5 or -4 x 5
If X = 4 then 5X is equal to 5 x 4 which is 20. So 20 + 2 = 22.
