Answer 1

Given,

The amount Tim get for his work is 5x^2 - 4x +8.

The amount Melina get for his work is 9x+13.

Required

The total amount of both get for their work.

The total amount is calculated as,

`Total\text{ amount = amount of Tim +amount of Melina}`

Substituting the values,

`\begin{gathered} Total\text{ amount = 5x}^2-4x+8\text{ +9x+13} \\ =5x^2+5x+21 \\ =5x^2+21+5x \end{gathered}`

Hence, the total amount of work is 5x^2+21+5x.
