Answer:
x = 3 un
Step-by-step explanation:
25 ÷ 5 = 5
Each side must be 5 units.
5 un - 2 un = 3
x = 3 un
Check:
3 un + 2 un = 5 un
5 un + 5 un + 5 un + 5 un + 5 un = 25 un
You have to square it all up then add it up if you want you can use the calculator
So 25 is 30 and 48 is 50 because you round to the nearest tenth
