The solutions for -5 +2x^{2} = -6x is option 3. x= \frac{-6 \pm \sqrt{36-4 (2)(-5)}}{4} .

Step-by-step explanation:

Step 1:

First, we must bring the equation to the form of ax^{2} +bx +c =0.

So -5 +2x^{2} = -6x becomes 2x^{2} +6x-5=0.

The value of a is the coefficient of the x^{2} term, the value of b is the coefficient of x term and c is the coefficient of the constant term.

Comparing the above equation to ax^{2} +bx +c =0, we get a = 2, b = 6, and c=-5.

We have the formula x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}.

Step 2:

By substituting the known values, we get

x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} =\frac{-6 \pm \sqrt{6^{2}-4 (2)(-5)}}{2 (2)}.

\frac{-6 \pm \sqrt{6^{2}-4 (2)(-5)}}{2 (2)} = \frac{-6 \pm \sqrt{36-4 (2)(-5)}}{4} .

This is the third option.

ABC is similar to ADEF. Find x. GEOMETRY
azamat

The value of x in the given diagram is 10

<h3>Similar triangles </h3>

From the question, we are to determine the value of the side labeled x

First, we will find the value of side |BC|

By the <em>Pythagorean theorem</em>, we can write that

|BC|² = 12² + 16²

|BC|² = 144 + 256

|BC|² = 400

|BC| = √400

|BC| = 20

Now,

Since ΔABC and ΔDEF are similar, we can write that

|BC| / |EF| = P ΔABC / P ΔDEF

But,

P ΔABC = 12 + 16 + 20 = 48

Thus,

|BC| / |EF| = P ΔABC / P ΔDEF becomes

20/ |EF| = 48/24

20/x = 2

x = 20/2

x = 10

Hence, the value of x in the given diagram is 10
