What is obtained by expanding \(3(x+2)\)?

Answer and explanation

Correct answer: \(3x+6\)

By the distributive law, 3 must be multiplied by both terms inside the brackets: \(3(x+2)=3\times x+3 imes2=3x+6\). Therefore, option D is correct. Option A is incorrect because it does not multiply 3 by 2. Exam tip: distribute the outside coefficient to every term inside the brackets.
