Since we have 2 numbers, we'll be square rooting.
All we have to do to find the mean is multiply & square root the products.
30 × 6 = 180

You can use the same process and check my answer if you'd like; I rounded the square root, so you may get a different answer.
Answer:

Step-by-step explanation:
We can immediately take out
because it's obviously the smallest.
We are left with
and
because
is greater than 1, and
is less than 1. The answer is
.
The answer would be B, 4s + 44
X=3
10- 4x=7x-23
14x-7x=123-10
-11x=-23-10
11x=-33÷(-11)
x=3
