Answer:

Step-by-step explanation:
given equation

subtracting 17 from both sides

the solution for quadratic equation 
 is given by
 is given by
x = 
________________________________
in our problem
a = 1
b = 2
c = -16

thus value of x is

 
        
             
        
        
        
Answer:
48in²
Step-by-step explanation:
to find the area of a triangle you first divide the base by 2 then multiply it by the height
 
        
             
        
        
        
Hey I tried, hope it helps... can't work it out, all the best
 
        
        
        
You apply the sum of interior angles formula ie. (n-2)180. n=number of sides
since a pentagon has 5 sides it will be (5-2)180=540.
now add everything. x-5+x-6+2x-7+x+2x-2=540.
Solve for x: 7x-20=540
7x=540+20
7x=560
x=560/7
x=80
        
             
        
        
        
7 is the answer 4 and lower you round down 5 and up is up
