Answer:
36
Step-by-step explanation:
f(x)=2x^2
f(-3)=2(-3)^2
f(-3)= -6^2
f(-3)=36
 
        
                    
             
        
        
        
ASSUMPTION = 10 TO THE POWER OF 24
Venus = 4.87 x 10^24
Jupiter = 1898 x 10^24
 = 1.898 x 10^27
(1.898 x 10^27) / (4.87 x 10^24) 
= 389.7330595
=390 (3 s.f)

Answer:
6
 
(4×n²) + (4×n¹) + (5×n^0) = 173
 4n² + 4n + 5 = 173
 4n² + 4n = 168
 divide through by 4
 n² + n - 42 = 0
 n² + 7n - 6n - 42= 0
 (n + 7)(n - 6) = 0
 n = -7 or 6
 but the solution is 6 since base is not negative.
