A graphing calculator can show you a graph of each expression, which you can compare to the offered choices.
_____
You can make use of the relations ...
... sin(a)+sin(b) = 2sin((a+b)/2)cos((a-b)/2)
... cos(a)+cos(b) = 2cos((a+b)/2)cos((a-b)/2)
... cos(a)-cos(b) = -2sin((a+b)/2)sin((a-b)/2)
Then you have ...

and ...

Step-by-step explanation:
Clare uses
cups of flour to make 4 cakes.
It means she uses 1 cup of flour to make
cakes.
Let us simplify that expression first for future use.
Therefore, Clare uses 1 cup of flour to make
cakes.
If Noah follows the same recipe,
He uses f cups of flour to make c cakes
Using Ratio Method
→ Name : Cup : Cake
→ Clare : 1 :
→ Noah : f : c
By using cross multiplication
c X 1 =
f
c=
f
The equation c=
f represents the relationship between c and f
