Your answer would be y=2x-34
explanation:
distribute the exponent
(x-1)^2 -> 2x-2
then combine like terms
2x-2-32 -> 2x-34
hope that helped :)
Cos(12x) = cos(6x+6x) = cos6xcos6x -sin6xsin6x = cos^2(6x) -sin^2(6x)
1 - cos(12x) = 1 - (cos^2(6x) -sin^2(6x)) = sin^2(6x) +cos^2(6x) - cos^2(6x) +sin^2(6x) = 2sin^2(6x)
so choice A. is right sure
Answer:
x=16 because the proportional size, this also means that if the -84 becomes 16 in proportion size.
It’s 4R+7
