Answer:
Step-by-step explanation:
6 = 2(y+2)
6 = 2y+4
2 = 2y
y = 1
2-3 is -1. difference between two rational numbers that make a negative
Answer:
A) always
Step-by-step explanation:
Use the identity cos^2 (a/2) = 1/2 (1 + cos a) so
cos^ 2 22.5 = cos^2 (45/2) = 1/2 ( 1 + cos 45) = 1/2(1 + sqrt2/ 2)4 = 1/2 + sqrt2/4
cos 22.5 = sqrt ( 1/2 + sqrt2/4) Answer
Just because your teacher asks you to do an answer you don't have to. okay so step one.... get up... step 2.... run. its a trap
