Multiply. a. 4x2 – 3x + 5 b. 3x4 – 13x3 – x2 – 11x + 6 c. 3x4 – 10x2 + 6 d. 3x4 – 14x2 – 11x + 6

x = 8

Step-by-step explanation:

Hi there!

We're given that OB is the angle bisector of angle AOC.

An angle bisector splits an angle into 2 equal halves. Therefore, angles AOB and BOC are equal.

We're given that angle AOB is 8x degrees and angle BOC is 16x-64 degrees.

Set up an equation:

Combine like terms:

Therefore, x = 8.

I hope this helps!
