What is 16 divided by X^2 equals 8 divided by X + 6?

zaharov [31]

Solve: $\frac{16}{x^{2}} = \frac{8}{x + 6}$

$\frac{16}{x^{2}} = \frac{8}{x + 6}$

$\text{Cross multiply: } 16(x + 6) = 8x^{2}$
$\text{Simplify: } 2(x + 6) = x^{2}$
$\text{Expand: } 2x + 12 = x^{2}$

$\text{Solve for x: } x^{2} - 2x - 12 = 0$

$\text{Use the quadratic equation: } x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$
$x = \frac{2 \pm \sqrt{4 + 48}}{2}$
$x = \frac{2 \pm \sqrt{52}}{2}$
$x = \frac{2 \pm \sqrt{13 \cdot 4}}{2}$

$x = \frac{2 \pm 2\sqrt{13}}{2}$
$\therefore x = 1 \pm \sqrt{13}$

PLZ help its due at 11:59

blagie [28]

Step-by-step explanation:

Given:

Complementary angle = 68'

Angle measure = 90' - 68' = 22'

Supplementary angle = 180' - 22' = 158'

Angle classification = Acute angle

Given:

Supplementary angle = 161'

Angle measure = 180' - 161' = 19'

Complementary angle = 90' - 19' = 71'

Angle classification = Acute angle

Given:

Angle measure = 136'

Angle classification = Obtuse angle

Complementary angle = 136' - 90' = 46'

Supplementary angle = 180' - 136' = 44'
