Answer:
Width = 44.45 inches
Height = 25.00 inches
Step-by-step explanation:
(16x)^2 + (9x)^2 = 51^2
256x^2 + 81x^2 = 2601
337x^2 = 2601
x^2 = 7.718
x = 2.778
Width = 44.45 inches
Height = 25.00 inches
I think this is right
 
        
             
        
        
        
Answer:
80 ft x 40 ft
Step-by-step explanation:
Let 'L' be the length of the longer side and 'W' be the length of the shorter side (or the width).
The equations that compose the linear system are:

Solving the system:

The garden is a rectangle with dimensions 80 ft x 40 ft.
 
        
             
        
        
        
There are 100 pennies in a dollar. We can divide 12000 pennies by 100 to find out how much they are worth in dollars. 
12000/100 = $120
        
                    
             
        
        
        
Lines b and c
they both go up 2 and over 1 (rise over run is slope)
