Answer:
A=266CM
Step-by-step explanation: 
p=2l + 2w                                   l=2x+1             w=x+5
66=2[2x+1] + 2{x+5]                  l=2x9 + 1           w=9+5
66=4x+2 + 2x+10                      l=18+1                 w=14
66=6x+12                                   l=19
66-12=6x
54=6x                                      A=L x W
x=9                                         A=19 x 14
                                              A=266CM

Answer:
sorry i dont know this this is very hatd question necause i cant have studied
 
        
             
        
        
        
3/5 = 60/100 = 0.6
   65 
 x 60
=  00
3900
3900 / 100 = 39. 
While going through construction, the car travels at 39mph. 
        
                    
             
        
        
        
Answer:
V = a (x + 4)*5 but see below.
Step-by-step explanation:
You're not going to get any kind of answer that gives V = 122 or some other pure number.
Formula 
V = arh
Givens
a = pi * r
r = (x + 4)
h = 5cm
Solution
V = a * (x + 4)*5 
or 
V = pi * (x + 4)^2  * 5
There is no indication of which one to choose.
