Simplify the expression:

Question

4(1+3b)=

Answer 1

To simplify the expression \( 4(1 + 3b) \), we will distribute the 4 to both terms inside the parentheses:

\[ 4(1) + 4(3b) \]

Calculating each term:

\[ 4 \cdot 1 = 4 \] \[ 4 \cdot 3b = 12b \]

Now combine the results:

\[ 4 + 12b \]

Thus, the simplified expression is:

\[ 4 + 12b \]
