Step-by-step explanation:
Answer: C. 
Step-by-step explanation:
1. You have the following division:
(As you can see, to find the conjugate of 4-3i you must change the sign between the terms).
2. To solve this division, you must multiply the numerator and the denominator by the conjugate of the denominator, as following:
3. Keeping on mind that 
, you have:
4. Simplifying:
5. The result is:

Answer: Choice A</h3>
Explanation:
When we rotate a rectangle around an axis of symmetry, we end up with a cylinder. Think of a revolving door or a turbine. The flat door moves through 3D space to produce or carve out a 3D cylinder.
This figure is composed of two rectangles, so we'll end up with two cylinders. They will both share the same center, so we'll have a sideways two-layer wedding cake structure when everything is said and done. This points to choice A as the final answer.
18² - 4 * 3 * 7 =240
x1 = (-b-root of 240)/2a = ............
x2 =(-b + root of 240)/2a = ........
