Answer:
Step-by-step explanation:
Part A.
Expression  = 10
 = 10
Because 100 =  and
 and ![[(10)^2]^{\frac{1}{2}}=10^1=10](https://tex.z-dn.net/?f=%5B%2810%29%5E2%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D10%5E1%3D10)
[Since,  ]
]
Part B.
When simplified, the answer is RATIONAL.
[Since, 10 can be written as  ]
]
 
        
             
        
        
        
Subtract 12 from each side
so it should look like this
-12v=-2v-18
now add 2v to each side
so it should look like this
-10v=-18
now divdie each side by -10
and you should get
v=9/5 or 1 4/5
        
                    
             
        
        
        
Answer:
23 inches
Step-by-step explanation:
Circumference = 2πr
72 = 2×3.142×r
Divide through by 2 × 3.142
r = 
r = 11.458 inches
Diameter = 2r
Diameter = 2* 11.458 = 22.92
= 23 inches to the nearest inch
