v = 10
Step-by-step explanation:
8 = 8v - 4(v+8)

Add 32 on both sides
40 = 4v
Divide by 4 on both sides
10 = v

Hello!</h2>
The answer is: True.
<h2>Why?</h2>
A counterexample is a way that we can prove that something is not true about a mathematical equation or expression, it's also considered as an exception to a rule.
So:

Then, evaluating we have:

Hence, we can see that the equation is not fulfilled, so, 45° is a counterexample for
and the answer is true.
Have a nice day!
