Answer:
+22
Step-by-step explanation:
Given g(x) = -x^2 + 4x - 11, g(4) is -(4)^2 + 4(4) - 11, or just -11.
Then -2 times g(4) = -2(-11) = +22
 
        
             
        
        
        
The amount one person will pay for a day is $4
The amount two people will pay for a day is $8
The amount Beth paid for 3 days is 4*3=12
The amount Maria paid for 3days is also 4*3=12
So to find the amount they will pay for 3days, add 12 and 12 to get 24. 
The girls will pay $24 for the 3days. 
Hope it helps
        
             
        
        
        
Answer:
x = 130
Step-by-step explanation:
Sum of all the angle of quadrilateral = 360°
 50 + 45 + 35 + ∠ADC = 360
                 130 + ∠ADC = 360
                          ∠ADC = 360 - 130
                          ∠ADC = 230
x = Reflex ∠ADC
   = 360 - 230
   = 130
 
        
                    
             
        
        
        
 
let 
(hypotenuse ) c = 10 in
(perpendicular) a = 8 in
(base) b =?
 
By using Pythagoras theorem
c^2= a^2+b^2
(10)^2 = (8)^2 +(b)^2
100 = 64 +(b)^2
100- 64 = (b)^2
36 = (b)^2
 √36 = b
 6 = b
hence b= 6 in
 
        
             
        
        
        
B.90 because 90 degrees is above the original angel
