Question

Evaluate the expression. \(2(r+s)\) when \(r=2\) and \(s=4\)

Short answer

The evaluated expression is 12.

Step-by-step solution

Substitute the given values

Replace \(r\) with 2 and \(s\) with 4 in the expression \(2(r+s)\), resulting in \(2(2+4)\).

Perform the addition operation

Perform the operation within the parenthesis first, which is addition. Result is \(2(6)\).

Multiply

Finally, perform the multiplication operation: \(2 \times 6 = 12\).
