Answer:
155 + + 14
Step-by-step explanation:
The variable x would represent the number/value we don't know, and in this case, we don't know what number is raised to the third power. This being said, x would represent that number.
The question, although worded a bit confusingly, asks to add 155, the number (x) to the exponent of 3, and 14. Mathematically, this would be 155 + + 14.
Set them up like this example:
4 8
_ = _
6 12
cross multiply by multiplying 4 by 12 and 6 by 8.
If they are equal then it is proportional.
