For a square:
A = s2, where s = side (the length and the width are the same)
625 = s2
±25 = s
length of rectangle = 1.4 · length of square
length of rectangle = 1.4(25)
length of rectangle = 35
        
             
        
        
        
The answer:
the main rule:
for all value positive of a real  b,  √b²= b, and   √b*c=   √b * √c, if c is a real positive
let A=√25x^4,  we know that  25x^4=5² * x² * x² 
therefore,  
√25x^4= √5² * x² * x² =√5² √x² √x² = 5* x*x= 5x²
the final answer is A=√25x^4=5x²
        
             
        
        
        
There is no graph, so it is impossible to answer this question. I apologise.
 
        
             
        
        
        
If the 2 lines are parallel, their slopes are the same.
The slope of both is  
          3+3
m = ---------- = 3
          2 - 0
If the new line <span>passes through the point (−1, −1), then the equation in point slope form is:
y+1 = 3(x+1).</span>
