$2 x^{2} \div(7-2 x)+2$ if $x=7$

Step 1 ：The question is asking for the value of the expression \(2 x^{2} \div(7-2 x)+2\) when \(x=7\).

Step 2 ：To solve this, we need to substitute \(x=7\) into the expression and simplify.

Step 3 ：After substituting \(x=7\) into the expression and simplifying, we find that the result is -12.0.

Step 4 ：Final Answer: \(\boxed{-12.0}\)
