Answer:
Proving a trigonometric identity refers to showing that the identity is always true, no matter what value of x x x or θ \theta θ is used. Because it has to hold true for all values of x x x, we cannot simply substitute in a few values of x x x to "show" that they are equal.

Answer:
False
Step-by-step explanation:
1.08/3=0.36 for an apple at HEB
1.15/5=0.23 for an apple at Kroger
36 cents is greater than 23 cents so HEB's apples are more expensive. They are 13 cents more than the Kroger apples. 0.36-0.23=0.13
Solve both sides and check to see if the solutions match.
(10 • 2) = 20
20 • 3 = 60
Now check the other side:
(2 • 3) = 6
10 • 6 = 60
Compare the solutions:
60 = 60
This is true, so the answer is A. True.
