Answer:
100 yds^2
Step-by-step explanation:
To find the area of a square, we need to know the length of one side of the square.  Since the perimeter is 4 times the length of one side, or 4s, and since 4s = 40 yds, s must be 10 yds.
Then the area of the square is (10 yds)^2 = 100 yds^2.
 
        
             
        
        
        
Answer:
0.4
Step-by-step explanation:
n × 0.2=0.08
n = 0.08÷0.2 
n = 0.4
 
        
                    
             
        
        
        
product is multiplication
 2 negative numbers multiplied by each other equal 2
 since it is multiplication the numbers would need to be 2 or less
 therefore the 2 numbers are -1 and -2
-1 * -2 = 2
 
 
        
             
        
        
        
Sorry I'm not sure if I'm right just my thinking...
set the number to be x so that (5x+2)(3x-4)??
