Answer:
528 square inches
Step-by-step explanation:
SA = 2(10·16) + 2(10·4) +2(4·16) 
= 2(160)+2(40)+2(64)
= 320 + 80 + 128
= 528 square inches 
 
        
             
        
        
        
Answer:
The roots of the equation are x =  and x =
 and x = 
and there are no real roots of the equation given above
Step-by-step explanation:
To solve:
5x² − 3x + 17 = 9
or
⇒ 5x² − 3x + 17 - 9 = 0
or
⇒ 5x² − 3x + 8 = 0
Now,
the roots of the equation in the form ax² + bx + c = 0 is given as:
x = 
in the above given equation
a = 5
b = -3
c = 8
therefore,
x = 
or
x = 
or
x =  and x =
 and x = 
or
x =  and x =
 and x = 
here i = √(-1)
Hence,
The roots of the equation are x =  and x =
 and x = 
and there are no real roots of the equation given above
