Answer:answer is a (x+8)^2=86
Step-by-step explanation:
x+8=±√
86
 
2 Break down the problem into these 2 equations.
x+8=\sqrt{86}x+8=√
86
 
x+8=-\sqrt{86}x+8=−√
86
 
3 Solve the 1st equation: x+8=\sqrt{86}x+8=√
86
 .
x=\sqrt{86}-8x=√

 −8
4 Solve the 2nd equation: x+8=-\sqrt{86}x+8=−√
86
 .
x=-\sqrt{86}-8x=−√
86
 −8
5 Collect all solutions.
x=\sqrt{86}-8,-\sqrt{86}-8x=√

Answer:
cuboid:6 sides 12 edges, parallelogram: opposite edges must be parallel and opposite must be the same size
Step-by-step explanation:
 
        
             
        
        
        
Y = 15x + 50
85 = 15x + 50
35 = 15x
X = 2.3333
X= 2 hours
        
             
        
        
        
They would be considered similar triangles.
        
                    
             
        
        
        
Given the position function 
s(t) = 7 - 14t
The instantaneous velocity is the derivative the the position function:
s'(t) = v = - 14
The velocity in an instant in time is 14 m/s in the opposite direction.
