Flashcard 19 - Mathematics: Quantitative Reasoning Flashcard Set for the TSIA2

\[4x + 12\]

The distributive property for multiplication over addition is \(x(y+z)=xy+xz\). We multiply each entry of the sum inside the parentheses by the number (or variable) outside the parentheses. So,

\[4(x+3)\] \[= 4(x) + 4(3)\] \[= 4x + 12\]
