It’s a right, scalene triangle. It also has two acute angles to go along with the right angle
A neutral atom contains equal amount of proton and
electron.
A negative ion contains extra electrons hence there is
additional outer shell so it is expected that the radius is bigger than that of
a neutral atom.
While a positive ion contains less electron so there is
less outer shell so the radius is smaller than that of a neutral atom.
Arranging the radius in increasing order:
<span>positive ion, neutral atom, negative ion</span>
In Step 6, the equation is ...
-12 = x - 36
In step 7, the equation is ...
-12 +36 = x -36 +36
Clearly, to get to step 7, 36 has been added to both sides of the equation.
Adding 36 to both sides of the equation is justified by ...

<em>More about the addition property of equality</em>
The addition property of equality says you can add the same value to both sides of an equation without changing the values of the variables that make the equation true. Here, x=24 makes the equation of step 6 true, and x=24 makes the equation of step 7 true.
This is so easy convert the mixed number to an improper fraction then multiply across . I hope this helped
