Hey there!
[tex]Answer:\boxed{120}[/tex]
[tex]Explanation:[/tex]
[tex]5(x+y)2[/tex] when x = 3 and y = 9
Let's first move to x and y.
[tex]x=3\\y=9\\3+9=12[/tex]
Now multiply 5 by x and y(3+9).
[tex]5*12(\text{x and y combined)}=60[/tex]
Now we have the number 2 left, so we have to multiply 60 by 2.
[tex]60*2=120[/tex]
[tex]\boxed{120}\text{ is your final answer.}[/tex]
Hope this helps!
