Answer:
wheres the picture
Step-by-step explanation:
the whole exam will be 100%, and let's say that's "x" questions, but we also know that 9 is 60% of that so

59pounds * 5days = 295pounds
6.95pounds * 3breakfasts = 20.85pounds
12.50pounds * 1eveningmeal = 12.50pounds
295pounds + 20.85pounds + 12.50pounds = 328.35pounds
Wrote out the units just for clarity! Liz payed 328.25 pounds altogether.
Step-by-step explanation:
9x^3+6x^2-3x
Cannot be simplified because there are no like terms but can be factored as
=3x(3x−1)(x+1)
