Evaluate 5(x + y)2 when x = 3 and y = 9

irakobra [83]

Hey there!

$Answer:\boxed{120}$

$Explanation:$

$5(x+y)2$ when x = 3 and y = 9

Let's first move to x and y.

$x=3\\y=9\\3+9=12$

Now multiply 5 by x and y(3+9).

$5*12(\text{x and y combined)}=60$

Now we have the number 2 left, so we have to multiply 60 by 2.

$60*2=120$

$\boxed{120}\text{ is your final answer.}$

Hope this helps!
