Answer:

The perimeter is 27 km

The area is 21 km^2

Step-by-step explanation:

The perimeter of a triangle will just be all of the sides added up.

12 + 9 + 6 = 27 km

The area of a triangle is:

A = 1/2 * base * height

The base is 6 km, and the height is 7 km. Substituting the values in and solving, we get:

A = 1/2 * 6 * 7

A = 3 * 7

A = 21 km^2

What is the value of x?<br><br>enter your answer in the box<br><br>X__​
vfiekz [6]
<h3>Answer: x = 5</h3>

=====================

Work Shown:

Angle Bisector Theorem

9/(2x-1) = 15/3x

9*3x = 15(2x-1) ... cross multiply

27x = 30x-15

27-30x = 30x-15-30x ... subtract 30x from both sides

-3x = -15

-3x/(-3) = -15/(-3) .... divide both sides by -3

x = 5

Kobotan [32]

Answer:

a.  2x^2 - 16x + 24.

Step-by-step explanation:

k(x) = 2x^2 − 8

p(x) = x − 4

To find ( k o p)(x) we replace the x in k(x) by x - 4:

= 2(x - 4)^2 - 8

= 2x^2 - 16x + 32 - 8

= 2x^2 - 16x + 24.
