Answer:

D) -4(3x + 6)

Step-by-step explanation:

Check:

Distribute the term outside the parenthesis (directly next to it) to all terms within the parenthesis:

A) -6(2x - 4) = (-6 * 2x) + (-6 * -4) = -12x + 24

B) -(12x - 6) + 18 = -12x + 6 + 18 = -12x + 24

C) -3(4x - 3) + 15 = (-3 * 4x) + (-3 * -3) + 15 = -12x + 9 + 15 = -12x + 24

D) -4(3x + 6) = (-4 * 3x) + (-4 * 6) = -12x - 24

If angle AEB has its vertex on the center of a circle and its endpoints on the circle, what is it?

Inessa [10]

1. Vertex E is the center of the circle, A and B are on the circle.

2. Any angle with these properties (i. E is center, AE and AB are radii) is called a central angle.

3. Check the picture.

4. An important property of these angles is that the measure of the arc AB = m(AEB)
