Step-by-step explanation:
Ruler's formula states that
We also know that
therefore,
(1)
Similarly, we can write
(2)
Adding Eqn(1) and Eqn(2) together, we get
or
To get the expression for the sine function, we subtract Eqn(2) from Eqn(1) to get
or
X^2+3x+3+[(2x^2+13+15)/(x+5)] is equivalent to option 4. im sorry if i got my math wrong but i hope this helps.
