Cubing a number does not mean multiplying it by 3 - it means multiplying it by itself, and then multiplying it by itself again. For example, 9 cubed is equal to 9 x 9 x 9 = 729.

2(x+9)=56 2x+18=56 -18 -18 2x=18 x=9 check: 2(9+9)=56 2(18)=56 56=56 :)

The number is 1.

If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18

N + 9

9 to the 2 power is 81 9x9=81 When you are calculating powers you are really multiplying the first number by itself the number of times the second number says. so for 9 to the 2 power you are multiplying 9 by itself 2 times
