Step-by-step explanation:
Emery has solved it incorrectly;
x = 100
4.0 rounded to the nearest tenth
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.
