Answer:
1 + (11-4)^2 +3x5
Step-by-step explanation:
1 + (11-4)^2 +3x5
1 + (7)^2 + 3 x 5
1 + 49 + 15
50 + 15 = 65
 
        
             
        
        
        
There are 4 lateral faces that are triangles.  Each triangle is: A = 

A = 

   = 176
There is one base that is a square. A = L x W
A = 16 x 16
   =  256
Surface area = 256 + 4(176)
                     =  256 + 704
                     = 960
Answer: B
 
        
        
        
F(x) = x^2 + 3 is a function.
domain of f(x) = x^2 + 3 is all real numbers.
range is all real numbers greater or equal to 3.

X=24
First you find the third side of the smaller triangle by using the Pythagorean theorem. You find that is it 100. Then you subtract that from 26 squared. After you get that, you square root the answer to get 24
