Answer:
The value of c is 12.25
Step-by-step explanation:
we know that
 A perfect square trinomial is of the form

In this problem we have

so
equate the equations

we have 
the following equations
 -----> equation A
 -----> equation A 
and
  -----> equation B
 -----> equation B
<u>Solve the equation A</u>



<u>Solve the equation B</u>
 
 
therefore

The value of c is 12.25
 
        
                    
             
        
        
        
The answer is probably c if I’m correct
        
             
        
        
        
Answer:
Gianna makes $18 per hour.
Step-by-step explanation:
Given Gianna makes 90$ for 5 hours. That means she should make  $  = 18$ every hour.
 $  = 18$ every hour.
Therefore we have:
a.
HOURS                    DOLLARS
   1                                   18
   2                                  36
   3                                  54
   4                                   72
   5                                   90
   6                                   108
   7                                   126
b.
For the tabular column mark Hours on the x - axis and Dollars on the Y - axis. It can be plotted from the above table easily.
c.
If Gianna works for 8 hours she would have made 8 X 18 = 144$.
So, she will earn 144$ in 8 hours.
d.
To make 60$ she would have to work  hours = 3.33 hours.
 hours = 3.33 hours.

Answer:
x=104
Step-by-step explanation:
Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)
10.5 = 1/2( x-83)
Multiply each side by 2
2* 10.5 = 2*1/2( x-83)
21 = x-83
Add 83 to each side
21+83 = x-83+83
104 =x
