Answer:
B
Step-by-step explanation:
We can use the following co-function identity:
![\sin(x)=\cos(90-x)](https://tex.z-dn.net/?f=%5Csin%28x%29%3D%5Ccos%2890-x%29)
Substuting 35 for x yields:
![\sin(35)=\cos(90-35)](https://tex.z-dn.net/?f=%5Csin%2835%29%3D%5Ccos%2890-35%29)
Subtract:
![\sin(35)=\cos(55)](https://tex.z-dn.net/?f=%5Csin%2835%29%3D%5Ccos%2855%29)
Hence, our answer is B.

Step-by-step explanation:
42 ÷ w = 7 for w = 6. First, Shaylee must substitute ( ) for ( ). To simplify, Shaylee must divide ( ) by ( ) .
Simple...
you have: -7=c-6
You want to isolate the variable c
-7=c-6
-7=c-6
+6 +6
-1=c
Thus, your answer.
Answer: ![4a^2 -4a+5](https://tex.z-dn.net/?f=4a%5E2%20-4a%2B5)
Step-by-step explanation:
![f(2a)=(2a)^2 -2(2a)+5\\\\=4a^2 -4a+5](https://tex.z-dn.net/?f=f%282a%29%3D%282a%29%5E2%20-2%282a%29%2B5%5C%5C%5C%5C%3D4a%5E2%20-4a%2B5)
