Answer:

x = 18; y = 20

Step-by-step explanation:

Triangles KLM and KNO are similar, so the ratios of the lengths of corresponding sides are equal.

KL/KN = LM/NO

10/30 = 6/x

Cross multiply.

10x = 6 * 30

10x = 180

x = 18

KL + LN = KN

10 + y = 30

y = 20

NEED HELP PLEASE!

Answer:

$(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16$

Step-by-step explanation:

Complex numbers identity:

The complex numbers identity is:

$i^2 = -1$

Square of the sum:

$(x + y)^2 = x^2 + 2xy + y^2$

In this question:

$(x + (3+5i))^2$

$x^2 + 2x(3+5i) + (3+5i)^2$

$x^2 + 6x + 10xi + 9 + 30i + 25i^2$

$x^2 + 6x + 9 + (10x+30)i - 25$

$x^2 + 6x + (10x+30)i - 16$

$(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16$

Find the measure of line KM. A. 14 B. 9 C. 12 D. 10

HACTEHA [7]

$\\ \sf\longmapsto \dfrac{3}{x-4}=\dfrac{6}{x-5}$

$\\ \sf\longmapsto 3(x-5)=6(x-4)$

$\\ \sf\longmapsto 3x-15=6x-24$

$\\ \sf\longmapsto 3x-6x=-24+15$

$\\ \sf\longmapsto -3x=-9$

$\\ \sf\longmapsto x=\dfrac{-9}{-3}$

$\\ \sf\longmapsto x=3$

$\\ \sf\longmapsto KM=3+6=9$
