Answer:
1,726 cm
Step-by-step explanation:
it boils down to this equation:
2(19×29)+2(19×6.4)+2(29×6.5)
bc if you look closely, it's just each side twice (hope that makes sense)
then you work down from there
2(551)+2(123.5)+2(188.5)
1,102+259+337
1,726
 
        
                    
             
        
        
        
Answer:
x < -16
Step-by-step explanation:
-6-x>10
adding 6 in both sides:
-6-x+6 > 10+6
-x > 16
If you want to remove the negative sign from x, you'll have to change the inequality sign.
x < - 16
Hope this helps.
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
From inspection of the graph, the given points are:
If we draw a line through the given points, the line is a curve rather than a straight line. If the line was a straight line, the graph would be modeled as an arithmetic sequence. Therefore, as the line is a curve, the given points are modeling a geometric sequence.
<u>General form</u> of a geometric sequence: 
  
where:
- a is the first term
- r is the common ratio
 is the nth term is the nth term
Rewrite the given points as terms of the sequence:
- (2, 9)  ⇒  a₂ = 9
- (3, 3)  ⇒  a₃ = 3
- (4, 1)  ⇒  a₄ = 1
To find the common ratio r, divide consecutive terms:

Calculate the first term (a) by substituting the found value of r and the given values of one of the terms into the formula:




Substitute the found values of r and a into the general formula to create the sequence modeled by the graph:

Supplementary angles means that the angle sum of the two angles will equal 180 degrees :)
 
        
                    
             
        
        
        
Answer:
y = 3
Step-by-step explanation:
y/9 = 2/6 
y/9 = 1/3 (dividing by 2in both numerator and denominator.)
CROSS MULTIPLYING WE GET
3y = 9*1
3y = 9
 y = 3
