If you add them together the sum is 8 1/8 and if you round it it’s 8
Answer:
steps below
Step-by-step explanation:
Are you going to solve the value of A or just a proof the equation
cos 2A = cos² A - sin² A
2cos²A-cos2A-1 = 2cos²A - (cos² A - sin² A) - 1 = cos² A + sin² A - 1
2cos²A-cos2A-1 = 1 - 1 = 0
A: 90° or 270° or 450° .....
The answer should be 15x + 10y ≤ 120
Since the pizza is x and chicken fingers is y then this should be the answer.
I would explain more but you only have five minutes left :)
