Answer:
triangle A= 1/2bh
 1/2(18)(14)= 126
semi circle 3.14(9)^2 divided by 2 = 127.17
Triangle Area plus semi circle Area = 126+127.17= 253.17
 
 
        
             
        
        
        
Answer:
8
Step-by-step explanation:
let the number be n , then
 n + 3 = n - 3 ( multiply through by 4 to clear the fraction )
 n + 3 = n - 3 ( multiply through by 4 to clear the fraction )
n + 12 = 4n - 12 ( subtract 4n from both sides )
- 3n + 12 = - 12 ( subtract 12 from both sides )
- 3n = - 24 ( divide both sides by - 3 )
n = 8
That is the number is 8
