Answer:
1) 
2) 
see the explanation
Step-by-step explanation:
we know that
The perimeter of the square is equal to
where
s is the length side of the square
we have
substitute
solve for s
The area of a square is equal to
substitute
we have that
therefore
2 equations that can determine the perimeter of the square are
1) ----> 
2) ----> 
<span>18.374 </span><span>r</span><span>ounded to the nearest tenth is </span><span>18.400.</span>
<span>Because 7 is after 5 so we will round to the next tenth......18.400

(1/8)x + 2 = 9 yields a solution of 56.
(1/9)x – 8 = 7 and (1/9)x – 7 = 8 both have a solution of 135.
This is an answer should help you
