She should have
nickles: 6 . =30
dimes: 30 . = 300
=330 . or $3.30
Either 2 or 41 you worded that like
28. Since it’s smaller than the opposite side, it needs to be divided by 2. That’s how I was taught
The last term is -100 so its either a or d.
Try a:-
(x^2 - 25)(x-2)(x - 2)
= x^2 - 25 (x^2 - 4x + 4)
= x^2 + 4x^3 + 4x^2 - 25x^2 + 100x - 100
= x^4 + 4x^3 - 21x^2 + 100x - 100
Its a.
