Answer:
The width cannot be negative, so w = 9, l = 16.
Step-by-step explanation:
w = the width
l = w +7
 
A = l · w
A= w ( w + 7 )
144 = w2 + 7w
0 = w2 + 7w - 144
0 = ( w - 9 )( w + 16 )
 
The width cannot be negative, so w = 9, l = 16.
 
        
             
        
        
        
Answer: <em>50°</em>
Step-by-step explanation:
<em>Since angle 3 is in a right triangle we can assume one angle is 90°</em><em> </em><em>and then the other missing angle will be 40°</em>
<em>Because you take 180°-140°(the angle next to it) which will equal 40°</em>
<em>Now every triangle must add up to 180°</em>
<em>so lets take the angles we have now</em>
<em>90° +40°=130°</em>
<em>now take that 130°</em>
<em>180°-130°=</em><em>50°</em>
<em>Now check your work</em>
90°+40°+50°=180°
Angle 3 is 50°
 
        
             
        
        
        
Answer:
See answer below
Step-by-step explanation:
This is a separable equation, so we solve it like this:

Then  for any constant k (this is the general solution). This solution is defined in (-∞,∞) (there are no singularities) and when x tends to infinity, no terms of the solution vanish, hence there are no transient terms.

Answer: there are 37 high school students on the bus
Step-by-step explanation:
h+m=54   total number of students
h= 2m+3 total number of HS students
2m+3+m=54    Substitute 2m+3 in for h
3m+3=54
3m=51
m=17
h+17=54
h= 37
