18sqrt(x)
I'm assuming that 3(sqrt(x))5 is equal to 15sqrt(x). If that is the case, just perform the multiplication within each term and treat the sqrt(x) as a variable when you add the all together. It is okay because they are like terms.
The mean is 14
add all the numbers up and divide the sum by 6 because that’s how many numbers you’re adding together.
12+10+14+18+14+16
= 84
84/6 = 14
