The answer is 4. 
The formula for the area of a rectangle is A = lw. Substitute, so then it's 28 = (3x-5) * x, and you evaluate. 
Hope this helps you! And rate so I can see if I did well!
        
             
        
        
        
Answer:
41.4 in
Step-by-step explanation:
(sin 80) <u>opposite</u>      =    <u>x</u>
           hypotenuse        42

Answer:
0.9953, 3.3629<x<4.0371
Step-by-step explanation:
Given that slader the internal revenue service claims it takes an average of 3.7 hours to complete a 1040 tax form, assuming th4e time to complete the form is normally distributed witha standard devait of the 30 minutes:
If X represents the time to complete then 
X is N(3.7, 0.5) (we convert into uniform units in hours)
a) percent of people would you expect to complete the form in less than 5 hours
=
b) P(b<x<c) = 0.50
we find that here 
c = 4.0371 and 
b = 3.3629
Interval would be
