1) I will buy a new guitar on my 22nd birthday
2) They never have time to play the whole game
1) I will buy a new guitar on my 22nd birthday
2) They never have time to play the video game
Đề ko rõ ràng \(\sqrt{x^2}+x+\dfrac{1}{4}\) hay \(\sqrt{x^2+x+\dfrac{1}{4}}\)??
\(8x-16=44-4x\Leftrightarrow12x=60\Leftrightarrow x=5\)
\(-\dfrac{1}{24}\le\dfrac{x}{24}\le\dfrac{5}{24}\Leftrightarrow-1\le x\le5\)
\(x\in\left\{-1;0;1;2;3;4;5\right\}\)
