Answer:
The expression is (64 - x).
Step-by-step explanation:
The statement is:
"the difference of 8 squared and a number"
Let the number be denoted by <em>x</em>.
The value of 8 squared is:


Then the expression for the provided statement is:
(64 - x)
Thus, the expression is (64 - x).
In this problem the big angle will be equal to two times the smaller angle so the correct expression is:

Now we can rewrite the equation so:
