Answer:
6
Step-by-step explanation:
When you multiply the square root of something with itself, your answer will be the number inside the radical sign.
This means that we should get 3*2=6.
8x + 6 = 2 (4x + 3)
Since it's divisible by two
Multiply the number outside the parenthesis by each term inside the parenthesis:
2(v+5) = 2v + 10
