Answer:
C
Step-by-step explanation:
The values are not vectors so ST/SR should be 3
If you want to multiply (2*x + 5) and (2*x - 5), you can do this using the following steps:
(2*x + 5) * (2*x - 5) = 4*x^2 - 10*x + 10*x - 25 = 4*x^2 - 25
The correct result is 4*x^2 - 25.
The answer would probably be the last one cuz it’s true and it has more then one thing
