ANSWER
B.
EXPLANATION
The given expression is
(sin x + 1)(sin x − 1)
Note that:
This implies that,
We can factor -1 on the right hand side to get,
Note that from the Pythagorean Identity
We apply this identity to obtain:
The correct choice is B
Answer:
r = -16
Step-by-step explanation:
We will use "distributive" property and "adding like terms" concepts in solving for the unknown variable "r".
The distributive property is:
a(b+c) = ab + ac
So
2(10r-7) = 20r - 14
also
-2(1+10r) = -2 - 20r
So, our equation becomes:
Now we add like terms and move variables (r) to one side and numbers to another. Like terms mean:
3r + 5r = (3+5)r = 8r
So, we have:
So,
the value of r is -16
