Answer: 5 in.
Step-by-step explanation:
Given
The area of the square is 
The side length of the square is 
Area of square

Thus, value of a is 5 inch
2x+18+1-1 works if that's all you want
I think it’s 16 per side but that’s 64 ft around I hope this helps sorry if it’s wrong
The slope is 2 over 3 and the y-intercept is -9
Answer:
y = 6/5x +2
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
5y−6x−10=0
Add 10 to each side
5y−6x−10+10=0+10
5y -6x = 10
Add 6x to each side
5y-6x+6x=6x+10
5y = 6x+10
Divide each side by 5
5y/5 = 6x/5 +10/5
y = 6/5x +2
The slope is 6/5 and the y intercept is 2
