Equation : (7x-4)+(3x-3)+(x) = 180 
In the equation the sum of the internal angle in the triangle is 180 degrees. Use this equation to figure the sum of angle in any quadrilateral 180*(number of sides-2) 
Solve the equation 
Put all similar variable on one side 
7x+3x+x-4-3=180
11x-7=180 
11x=180+7 
11x=187 
x = 187/11 
x = 17 
Now find the angles by plugging in x
Angle F (7*17-4) = 115 degrees 
Angle G (x) = 17 degrees 
Angle E (3*17-3) = 48 degrees 
If you add 115+48+17 you will get a sum of 180 this shows your answer is right 
Angle F = 115 
Angle G = 17 
Angle E = 48
        
             
        
        
        
Hello, 
Since the degree of a polynomial is the highest exponent present, the degree of Mei’s polynomial should be 2.
        
             
        
        
        
Answer:
x=5 and y=-2
Step-by-step explanation:
3x+5y=5
-(7x+5y=25)
-4x=-20
x=5
plug 5 into one of the equations. 3(5)+5y=5
y= -2
