Resolver para \( x \) \[ 6 x-36=-4(x+4) \] Simplificar la respuesta al máximo \( x=\square \)

Use long division to divide. SEE EXAMPLE 1 15. \( x^{3}+5 x^{2}-x-5 \) divided by \( x-1 \)

Use the Unit Circle to find the exact value of the inverse trig function. Remember the domain of inverse cosine is limited to quadrants I and II (the top half of the unit circle). \( \cos ^{-1}(-1) \) a. \( 180^{\circ} \) b. \( 90^{\circ} \) c. \( 270^{\circ} \) d. \( 0^{\circ} \)
