, option B
Step-by-step explanation:
Complex numbers:
The most important relation that involves complex numbers is given by:

Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
 .
.
This polynomial has roots  such that
 such that  , given by the following formulas:
, given by the following formulas:



In this question:
The solutions are:

We have to find the polynomial. All option have  . So
. So

The correct answer is given by option b.
 
        
             
        
        
        
2x + 2(2x+3) = 360
2x +4x +6 = 360
6x  = 360 - 6
6x  = 354
x =  354/6
x = 59
answer: x = 59
        
             
        
        
        

Sum of three consecutive odd integers =

Answer:
15 cm
Step-by-step explanation:
The altitude is one leg of the right triangle formed by the altitude, half the base, and the triangle side. The Pythagorean theorem applies, so you have ...
... (17 cm)² = (altitude)² + (16 cm/2)²
... altitude = √(17² -8²) cm = √225 cm
... altitude = 15 cm
 
        
             
        
        
        
Answer:
