(b–2)(b+2)(b^2+4)

B^5-16

If that is b to the second power. Then you multiply all the b’s which gives you b to the 5th power: b^5. Then -2•2= -4.
-4•4= -16 Final b^5-16

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425

Anyone can me with these answers
