PLEASE ANSWER I REALLY NEED HELP ON THIS QUESTION!

In triangle ABC, angle A = 30 degrees and angle B = 60 degrees. Point X is on side AC such that line segment BX bisects angle ABC. If AB = 12, then find the area of triangle BXA.

(40 points) i need some . an answer definition is appreciated as well.

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
