Answer:
54
Step-by-step explanation:
x-1=3
2xy=24
3+24=27
27·2=54
 
        
                    
             
        
        
        
Slope = (y2-y1)/(x2 - x1) 
Slope = (9 - 6)/(-3- (-9)) = 3/6 = 1/2
Answer: 1/2
 
        
                    
             
        
        
        
The length of side walk is 500 feet
<em><u>Solution:</u></em>
Given that, A rectangle park measures 300 ft by 400 ft
Length = 300 feet
Width = 400 feet
A sidewalk runs diagonally from one comer to the opposite corner
We have to find the length of side walk
Which means, we have to find the length of diagonal of rectangle
<em><u>The diagonal of rectangle is given by formula:</u></em>

Where,
d is the length of diagonal
w is the width and l is the length of rectangle
<em><u>Substituting the values in formula, we get</u></em>

Thus length of side walk is 500 feet
 
        
             
        
        
        
Answer:
Width = 12 in
Length = 16 in
Step-by-step explanation:
Let, the Width of the rectangle = w in
Now, the length of the rectangle = (w + 4) in
Now, Perimeter = 56 in
Also, we know that
Perimeter of the Rectangle = 2 (Length +Width)
or, 2 (Length +Width) = 56
⇒ 2(w + 4 +w) = 56
or, 4w =56 -8
width  = 12 in
So, Length = w + 4 = 12 + 4 = 16 in
 
        
             
        
        
        
Check the picture below.
so notice, their perimeter is the same, because the perimeter is just one rod anyway, and all rods are the same length, thus
