Question

Can you evaluate 3 + (a + 4)(8- b ) when a= 5 and b=6

Answer 1

The expression to evaluate is:

`3+a+4\mleft(8-b\mright)`

When

a = 5 and b = 6

We simply plug in the values of 5 and 6, into a and b respectivly. And do algebra to get our answer. The process is shown below:

`\begin{gathered} 3+a+4\mleft(8-b\mright) \\ 3+5+4\mleft(8-6\mright) \\ 3+5+4(2) \\ 3+5+8 \\ 16 \end{gathered}`

The answer is 16.
