The quotient of 2.28 × 5.59 using compatible numbers is approximately 12.75
<h3>What are products?</h3>
Quotients are result derived from the multiplication of two rational or integers. Given the expression
2.28 × 5.59
Convert to fraction
2.28 × 5.59 = 228/100  ÷  559/100
2.28 × 5.59= 127452/10000
2.28 × 5.59=  12.75
Hence the quotient of  2.28 × 5.59  using compatible numbers is approximately 12.75

Slope = (y2 - y1)/(x2 - x1)
slope = (7 - -2)/(-3 - 6)
slope = 9/-9
slope = -1
        
             
        
        
        
The formula for solving perimeter of a parallelogram is P=2(a+b) where "a" is for the altitude and "b" for the base. From the give figure, we can determine both a and b values as enumerated below,
a=5
b=4
We can solve for P as shown below,
P=2(5+4)
P=18 unit.
Therefore, the perimeter is equal to 18.
