Answer:
The first pair shows equivalent expressions.
Step-by-step explanation:
3(x+2), you would have to distribute 3 among x and 2, also known as expanding the expression. So you'd do 3*x + 3*2, which equals 3x+6
The first equation is 3(x+2)=3x+6
Therefore, the first pair shows equivalent expressions.

Answer:
3√2
Step-by-step explanation:
First, combine all the numbers in the square root, and then square root the number provided:
√(3 + 3 + 3 + 3 + 3 + 3) = √18
When square rooting, first, find prime factors of the number, 18. If there are pairs, they will be combined into a whole number:
√18 = √(3 * 3 * 2) = 3√2
3√2 is your answer.
