Step-by-step explanation:

using the pythagorean theorem you can plug in the numbers to get √(12^2 - 6^2) = √(144-36) = √108 = 6√3.

Solve the following proportion for u.

Ymorist [56]

$\frac{5}{13} = \frac{u}{11}$
$5 * 11 = 13u$
$\frac{55}{13} = \frac{13u}{13}$
$4\frac{3}{13} = u$

Can you find the area and explain how you got the area

rewona [7]

Answer:

102cm^2 - hope this helps

Step-by-step explanation:

find the area of the rectangle first in the middle

which equals 6 x 13 = 78cm^2

then find the traingles on the side

(6 x 4) / 2 = 12

there are 2 traingles so it would be 12 + 12 = 24

so all together the area would be 78 + 24 = 102cm ^2

Which point lies on the line described by the equation below?

vova2212 [387]

Answer:

F (5,-8)

Step-by-step explanation:

By rearranging,

y= 4x-28

Substitute each of the x values of the answers, eventually you will get to F and discover that when x = 5, y= -8

y= 4(5) - 28

y= -8

So, when x= 5, y= -8,

Point F is (5,-8)

Solve the equation 25x²+100x+200=0.

k0ka [10]

Answer:

$x = -2+2i ,x = -2-2i$

Step-by-step explanation:

given,

equation 25x²+100x+200=0

dividing the equation by 25 on both side

x²+4x+8=0

using

$x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x = \dfrac{-4\pm \sqrt{4^2-4\times 1\times 8}}{2}$

$x = \dfrac{-4+ \sqrt{4^2-4\times 1\times 8}}{2},x = \dfrac{-4-\sqrt{4^2-4\times 1\times 8}}{2}$

$x = \dfrac{-4+ \sqrt{-16}}{2},x = \dfrac{-4-\sqrt{-16}}{2}$

$x = \dfrac{-4+ 4i}{2},x = \dfrac{-4-4i}{2}$

$x = -2+2i ,x = -2-2i$
