Answer:
23h^2
Step-by-step explanation:
These are all like terms so we add/subtract them from left to right.
7h^2+6h^2+5h^2+6h^2-h^2
=   24h^2 - h^2
= 23h^2   (answer)
 
        
             
        
        
        
The equation for a line is y=mx+b. where m is the slope and b is the y intercept. 
The slope of 17 is provided. This means m=17. The point (0,0) tells you the y intercept is 0. This means b=0
Plugging these into the equation and simplifying:
y=17x+0
y=17x
Hope this helps :)
        
             
        
        
        
In the order of PEMDAS
the first thing you would do is divide 18/3 = 6
then multiply 6 x 4 = 24
then add 24 + 6 = 30
        
                    
             
        
        
        
Answer:
ferris wheel travel approx = 434.72 ft 
Step-by-step explanation:
given data 
wheel rotates = 9pi/8 radians
total height of the ferris wheel =  246 ft
solution
we can say here that height of the ferris wheel is same as the diameter of the wheel 
and wheel is circular in shape 
so we get here first radius of wheel that is 
radius = half of diameter    ..........................1
put here value and we get 
radius = 0.5 × 246 
radius = 123 ft 
and 
wheel travel distance = length of arc by a angle of wheel rotates 
so here length of arc will be 
arc length = radius × wheel rotates angle   .....................2
put here value and we get 
arc length  = 123 ×  
 
arc length = 434.7178 ft 
so ferris wheel travel approx = 434.72 ft
