Question

Which of the following is the correct usage of the distributive property of the expression: 3(x+1) ?

Answer 1

Answer:  =3x+3

Step-by-step explanation:

$3\left(x+1\right)$

$\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac$

$3\left(x+1\right)=3x+3\cdot \:1$

$=3x+3\cdot \:1$

$\mathrm{Multiply\:the\:numbers:}\:3\cdot \:1=3$

$=3x+3$
