24x+80

Step-by-step explanation:

Hey There!

so we can find an equivalent expression by using distributive property

we can distribute 8 to what's inside of the parenthesis

8*3x=24x

8*10=80

so we can conclude that an equivalent expression would be

24x+80

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
