Wanna help me out?? :)

Answer 3

What's the question?

Answer 4

\[7\sqrt{13x}-15\sqrt{2x}+2\sqrt{13x}-4\sqrt{2x}\]

Answer 5

like asking what is
\[7y-15z+2y-4z\] exactly

Answer 6

Just combine like terms

Answer 7

How?

Answer 8

for example \(7\sqrt{13x}+2\sqrt{13x}=9\sqrt{13x}\)

Answer 9

and \[-15\sqrt{2x}-4\sqrt{2x}=-19\sqrt{2x}\]

Answer 10

yes

Answer 11

put them together and get
\[9\sqrt{13x}-19\sqrt{2x}\] there is nothing more than can be done

Answer 12

since \(\sqrt{13x}\)and \(\sqrt{2x}\) are not like terms, you cannot combine them in one term

Answer 13

So that is all? Wow, that's much easier than I thought! Thank you so much! ;D

Answer 14
