PLEAE HELP WILL GIVE YOU BRAINLIEST. Simplify 3$\sqrt{x}$5 - 2$\sqrt{x}$7 + $\sqrt{x}$45 - $\sqrt{x}$28

Answer 1

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.
