Answer:
3y + 3z
Step-by-step explanation:
y + 2y + 3z you can only combine like terms y or 1y + 2y = 3y
3y + 3z these can't be combined because one is y and the other z
37 and 1 / 4 = 37 * 6 = 74 * 3 = 222
That's incorrect. The simplest way to show this is by evaluating the functions at a given point. Let's say x=0, then:
Sin(-x) = Sin(0) = 0
-cos x = -cos (0) = -1
Therefore, Sin(-x)≠-cos x.
