Question

Evaluate rs+14s when r=6 and s= 1/4

Answer 1

The given expression is

`\begin{gathered} rs\text{ + 14s } \\ \text{If we substitute r = 6 and s = }(1)/(4)\text{ into the express}\imaginaryI on,\text{ it becomes} \\ 6\text{ }*(1)/(4)\text{ + 14 }*(1)/(4) \\ (3)/(2)+\text{ }(7)/(2) \\ By\text{ adding both numbers, it becomes} \\ (10)/(2)\text{ = 5} \end{gathered}`

The solution is 5
