Answer:
Option B: is the correct answer.
Step-by-step explanation:
Given expression is:
We have to find the value of x.
Multiplying both sides by r
Now, we will subtract t from both sides of the equation
sr - t = 2x+t-t
sr-t = 2x
2x = sr-t
Dividing both sides of equation by 2
Hence,
Option B: is the correct answer.

Answer:
(a) If f and t are both even functions, product ft is even.
(b) If f and t are both odd functions, product ft is even.
(c) If f is even and t is odd, product ft is odd.
Step-by-step explanation:
Even function: A function g(x) is called an even function if
Odd function: A function g(x) is called an odd function if
(a)
Let f and t are both even functions, then
The product of both functions is
The function ft is even function.
(b)
Let f and t are both odd functions, then
The product of both functions is
The function ft is even function.
(c)
Let f is even and t odd function, then
The product of both functions is
The function ft is odd function.
