Expand the linear expression 3( 4M + 7)

Answer 1

To expand the linear expression \( 3(4M + 7) \), you need to distribute the \( 3 \) to both terms inside the parentheses:

\[ 3(4M) + 3(7) \]

Now, calculate each term:

• \( 3 \times 4M = 12M \)
• \( 3 \times 7 = 21 \)

Now combine the results:

\[ 12M + 21 \]

So, the expanded expression is:

\[ 12M + 21 \]
