If a circle is divided in half and that half is divided into two more halves what is the angle created

A circle is 360 degrees. When cut in half, 360/2 = 180, the new angle of the shape is 180. Cut the half circle in half again and you get 180/2 = 90. It sounds like you only need to cut it into half twice, (if not, then you divide it in half how ever many times it says to) The angle would be 90 degrees. Hope this helps!  

The answer to your question is the last option   (-2x² - 3)(4x + 1)

Step-by-step explanation:

Expression              - 8x³ - 2x² - 12x - 3

Order the terms     - 8x³ - 12x - 2x² - 3

Process

1.- Factor the first two terms and the last two terms

                               (-8x³ - 12x²) + (-2x - 3)

Common factor of the first group   -4x

Common factor of the second group   -1

2.- Factor each group

First group                  -4x(2x² + 3)

Second group            -1 (2x² + 3)

3.- Factor again by common factor

                         -4x(2x² + 3) - 1(2x² + 3)

                         (2x² + 3)(-4x - 1)  or -(2x² + 3)(4x + 1) or (-2x² - 3)(4x + 1)
