<span>The number of lines in a spectrum is dependent upon the material being tested. Elements are often the test subject, but (then again) planets and stars have spectra of their own. On an elemental level, a spectrum is based on the number of electron excitation possibilities. More complex structures have much more complex spoectral determinations. Spectral evidence, however, should never be admissible in court!</span>

Solve x + 5x + 6 = 0
Dominik [7]
X+5x+6=0
x+5x=6x
6x+6=0
-6 -6
6x=-6
\6. /6
x= -1
so the answer would be -1

Question 9 (Essay Worth 10 points) (03.06 HC) Seth is using the figure shown below to prove Pythagorean Theorem using triangle s
mario62 [17]

In the case above, the length of Angle DA is 6 and angle ABD ≈ Angle CAD.

<h3>What is the angle about?</h3>

Note that:

Δ ABC , A = 90

To find length of DA :

Let Δ ACB = x

So Δ ABC = 90 -x

For Δ ABC and ADC:

Δ ADB = Δ ADC  (90°)

Δ ABD = Δ DAC (90 - x)

For Δ ABC ≈  ADC:

\frac{AD}{DC} = \frac{BD}{AD}

AD² = BD. CD.

AD²= 9 . 4

AD²= 36

AD = 6

Therefore, In the case above, the length of Angle DA is 6 and angle ABD ≈ Angle CAD.
