cos 2 x = cos² x - sin² x = 1 - sin² x - sin² x = 1 - 2 sin² x.
Answer: A ) 1 - sin² x and D ) cos² x - sin² x
Thank you.
Answer:
x=7
Step-by-step explanation:
since the ray bisects we know <CAT and <TAR are equal
so we can set up the equation like this: <CAT + <CAT = <CAR
(5x)+(5x)=(9x+7)
calculate equation and you'll get x=7

Bro how are we supposed to know there is no picture -_-
Answer:
y= x⁴ -21x²-100
combine x's I think
x⁴= 1x? cuz if it's 1x⁴ that's 1x*1x*1x*1x = 1x
1x * -21x²
-21x * -21x = 441x
+1x = 442x
y= 442x -100
I'm not sure if I did that right
