Question

Welp, my last post I wrote wrong and everyone was answering it wrong... my bad

Here are the questions:

(3√6 +5√10)^2

y = √6x-18

I couldn't figure out how to solve them, and I looked up online and here are the answers. I just need to be able to solve it...

286 + 60√15

x ≥ 3

Answer 1

By this time, you should have been able to find your answers in what was written in the responses.

Answer 2

Steve, I wrote the problems incorrectly, so no, I can't

Answer 3

Your text above seems to indicate that the last problem was to find the domain of √(6x-18)

You know that square roots of negative numbers are not real, so the radicand must be positive That is,

the domain of √x is x >= 0

So, the domain of √(6x-18) is

6x-18 >= 0
x >= 3

Look again for the answer to part 1. It is there.
