Answer:
the Diagonal is 41 units
Step-by-step explanation:
Since the sides of a rectangle, to be a rectangle, meet at 90° we use Pythagorean Theorem a² + b² = c²  
Width and Length are the legs and the diagonal is the hypotenuse
9² + 40² = c²
81  + 1600 =  c²
1681 = c²
√1681 = √c²
41 = c
 
        
             
        
        
        
Answer:
If we look at the table we notice that 2 + 4 = 6, 3 + 4 = 7, 4 + 4 = 8 and so on so the equation is y = x + 4.
 
        
                    
             
        
        
        
Answer: A.
Step-by-step explanation:
Plot the y-intercept (0,-1) and use the slope of 1/4 to find a second point
 
        
                    
             
        
        
        
Well, we know that 2/3 is about equal to .666 and 2/4 equals .5  Since .666 is a greater number, Ricardo read more.
        
                    
             
        
        
        
The answer is 73.5
To make it a lot easier split the shapes into a rectangle and triangle. 
The rectangle is a tad easier because the measurements are given here. 
5 x 12 = 60 (rectangle area)
To find the triangle find the base then height. The base is 3cm and the height is 9cm (shown above)
9 x 3 = 27 
Divide that by 2 because it's a triangle and you get 13.5. 
Add those two numbers and voila you have your answer of 73.5.
