X/5 = 24/8 
  (because the triangles are similar)
x/5 = 3
x = 5*3 = 15 Answer
a/27 = 8/24 = 1/3 
a =  9  Answer

Step-by-step explanation:
 
        
                    
             
        
        
        
A) -4
d) -3.1
 for these questions you have to subtract the two numbers since they have different signs and the biggest sign is the ending sign
        
                    
             
        
        
        
R(t) = 4t
A(r) = π(r^2)
a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)
b) t = 4, 
A(4) = 16*3.14*(16)^2 = 12,861.44
