I think your answer is 28

I think the point k may be the centroid of the triangle, so that point would be 2/3 of the way from the vertex to the opposite side. If the ENTIRE length of AP is 18, then point K would be at the 2/3 x 18 = 12 mark. So if you're looking to find KP, it would be (18-12) = 6.

Graph the linear equation. Find three points that solve the equation, then plot on the graph. -x - 2y = -10
jok3333 [9.3K]
-x - 2y = -10  |add x to both sides

-2y = x - 10    |divide both sides by (-2)

y = -0.5x + 5

for x = 0, y = -0.5(0) + 5 = 0 + 5 = 5 ⇒ (0; 5)
for x = -2, y = -0.5(-2) + 5 = 1 + 5 = 6 ⇒ (-2; 6)
for x = 2, y= -0.5(2) + 5 = -1 + 5 = 4 ⇒ (2; 4)

6x^2 + 11.

Step-by-step explanation:

24x3 - 54x2 + 44x - 99      Re-arranging:

= 24x^3 + 44x - 54x^2 - 99

= 4x(6x^2 + 11) -  9(6x^2 + 11).
