There is only one number that satisfies x=4x, meaning the a number quadrupled is the same number.

That number is 0.

I guess if you want to be technical, then the square root of any negative number would also work. The square root of a negative number doesn't exist, it is what is called an "imaginary number". So in a way an imaginary number would be the same as four times an imaginary number.

If you want to get deep, then there's another case that works. Infinity. Which is a greater value, one infinity or four infinities? They're the same thing because they both never end.

The most important thing I need to know to solve a math problem is what operation you need to use in order to complete the problem successfully. I believe this because if you don’t know what operation you need to solve the problem you won’t get to your goal of solving the problem

Answer:

This is a vertical angle theorem

Step-by-step explanation:

Vertical angles are a pair of opposite angles formed by intersecting lines. In the figure, ∠1 and ∠3 are vertical angles. ... Vertical angles are always congruent . So, in this figure, ∠1≅∠3 and ∠2≅∠4 .
