Answer:
The length of one side of the square is [tex](4x-5) units[/tex]
Step-by-step explanation:
we know that
The perimeter of a square is equal to
[tex]P=4b[/tex]
where
b is the length of one side of the square
In this problem we have
[tex]P=8x-10+8x-10[/tex]
[tex]P=16x-20[/tex]
substitute
[tex]16x-20=4b[/tex]
solve for b
[tex]b=(16x-20)/4[/tex]
[tex]b=(4x-5) units[/tex]
