Rewrite with only sin x and cos x. sin 3x - cos x
a. 2 sin x - sin^3x - cos x
b. 2 sin x cos^2x + sin x - 2 sin^3x - cos x
c. 2 sin^3x cos^4x + 1
d. 3 sin x cos x - sin^3x - cos x

im trinna find out'

step-by-step explanation:

i can you answer this question sweetie!

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,
