To solve this expression, you need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). In this case, you first need to perform the multiplication before the division. So, 2/9 x 45 becomes (2/9) x 45, which simplifies to 90/9, and further simplifies to 10. Therefore, the answer is 10.

2/9 x 45/82 x 45 = 909 x 8 = 7290/72(divide both sides by 18)= 5/4
ten 2 / 9 x 45 = 2 / 9 x 45 / 1 = 2 x 45 / 9 x 1 = 90 / 9 = 10 / 1
-x2-14x-45 = -(x2+14x+45) delta = 142-4*1*45=16 so x2+14x+45=(x-(-14+4)/2) (x-(-14-4)/2) = (x+5)(x+9) so -x2-14x-45 = -(x+5)(x+9)
2/5 x 45 = 18
