Answer:
Length = 20 feet; x = 14
Step-by-step explanation:
Parameter = width + length + width + length
64 feet = 12 feet × 2 + (x + 6) feet × 2
64 = 24 + (x + 6) × 2
64 - 24 = (x + 6) × 2
40 = (x + 6) × 2
40 ÷ 2 = x + 6
20 = x + 6
20 = length
20 - 6 = x
14 = x
 
        
             
        
        
        
The length of the garden box would be 10ft if the width is 6ft.
        
             
        
        
        
<h2>
Answer with explanation:</h2>
Let p be the population proportion  of parents who had children in grades K-12 were satisfied with the quality of education the students receive. 
Given : Several years ago, 39% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. 
Set hypothesis to test :

Sample size : n= 1055
Sample proportion : 
Critical value for 95% confidence : 
Confidence interval : 

Since , Confidence interval does not contain 0.39.
It means we reject the null hypothesis.
We conclude that 95% confidence interval represents evidence that parents' attitudes toward the quality of education have changed.
