Answer:  -1 ± <em>i</em>√35

                  ⁻⁻⁻⁻⁻⁻⁻⁻

                     6

Step-by-step explanation:

From the quadratic equation,

X =  -b ±√b² - 4ac

     ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻

             2a

From the given equation, -3x² - x - 3 = 0

where a = -3, b = -1, c = -3

Now substitute for the values in the formula above

x = -(-1) ± √(-1)² - 4(-3)(-3)

      ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻

                   2(-3)

x = 1 ± √ 1 - 36

     ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻

           -6

x = 1 ±  √ -35

     ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻

           -6

x = -1  ±  <em>i√35   this is because it has a negative root.</em>

<em>       ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻</em>

<em>            6</em>

<em> The answer is b</em>

Can I get help solve to find X?
Taya2010 [7]
<h3>Answer:  x = 14</h3>

==========================================

Explanation:

The same tickmarks on each side of the triangle tells us that all three sides are the same length. This triangle is equilateral.

All equilateral triangles have each of their three angles at 60 degrees (they are considered equiangular). This is because 60+60+60 = 180.

Set 2x+32 equal to 60 and solve for x

2x+32 = 60

2x = 60-32

2x = 28

x = 28/2

x = 14

As a check,

2x+32 = 2*14+32 = 28+32 = 60

which helps confirm the answer.
