The simplified ratio is 2:3. Since the smaller number when it's not simplified is 18, let's divide 18 by 2 to get our factor.
18/2 = 9.
So we can multiply 9 by 3 to get the missing larger number.
9 x 3 = 27.
Your missing number is 27, hope this helps! 
        
             
        
        
        
(2x+1)(x+1)
Now multiply 2x to both x and +1 
2x^2+2x 
Do the same with 1 multiply it to x and +1
2x^2+2x +x+1
Simplify 
2x^2+3x+1

Bill tells Matt that he has 3 kids. This means that in this item, we have three unknowns, those are the ages of the three kids. First, the product of the ages is 72.
                            (x)(y)(z) = 72
Also, for the sum of their ages, we have
                              x + y + z =?
There are three variables in the equation which means that 3 equations should also be presented to determine the ages of the three children. 
        
             
        
        
        
Answer:
<em>The water is leaking at the rate of 0.0625 gal/min.</em>
Step-by-step explanation:
<u>Rate of change</u>
The rate of change (ROC) is a measure that compares two quantities, usually to know how fast one variable changes in time.
The container holds 8 gallons of water and is leaking at a constant rate to be calculated later.
When 48 minutes have passed, the container has 5 gallons of water left. This means it has leaked 8 gallons - 5 gallons = 3 gallons.
Calculating the rate at which it's leaking:

r = 0.0625 gal/min
The water is leaking at the rate of 0.0625 gal/min.
