11, you can write the question in the form of x=-2x+33, then add 2x to both sides to get 3x=33, now divide both sides by 3 and you get x=11.
half a number
True
Twice the number is something like 3x2, 4x2.... Squared is 3x3, 4x4. It's one number multiplied by itself twice
The number is 15 times 15 = 225
no its when its multiplied by itself 3 times for instance 33 is 3x3x3 which is 27.

The sum of a number times 3 and 27 is greater than or equal to 15.
You would need to divide by -1/2.
negative 2
The number is 15 times 15 = 225
In a perfect number, the sum of all the factors (including the number itself) is twice the number. E.g., the sum of the factors of 6 is 1 + 2 + 3 + 6 = 12 (equal to 2 x 6). Every prime number has two factors: 1, and itself. So, the sum of the factors is only one more than the prime number itself; for any number greater than 1, this can't be twice the number. For example, the prime number 7 has the factors 1 and 7, which add up to 8.
There are two consecutive odd numbers such that five times the smaller plus twice the greater is 25. What is the smaller number?
no its when its multiplied by itself 3 times for instance 33 is 3x3x3 which is 27.
If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18
A cube of a number is when you multiply it by itself twice. Eg) 2 cubed = 2x2x2=8
