Not sure if there is a question here. However, I'll assume you're looking for when it lands. It takes about 24.6 minutes to land.

Identify the vertical asymptotes of <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E3-16x%7D%7B-3x%5E2%2B3x%2B18%7D" id="TexForm

$\sf \frac{ {x}^{3} - 16x}{ { - 3x}^{2} + 3x + 18 }$

To find the vertical asymptotes set denominator as 0

$\sf - 3x ^{2} + 3x + 18 = 0$

Divide both sides of the equation by-3

$\sf \: {x}^{2} - x - 6 = 0$

Write -x as a difference

$\sf \: {x}^{2} + 2x - 3x - 6= 0$

Factor out x from the expression

$\sf \: x \times (x + 2) - 3x - 6 = 0$

Factor out -3 from the expression

$\sf \: x \times (x + 2) - 3(x + 2) = 0$

Factor out x+2 from the expression

$\sf(x + 2)(x - 3) = 0$

When the product of factors equals 0, at least one factor is 0

$\sf \: x + 2 = 0 \\ \sf \: x - 3 = 0$

Solve the equations for x

$\sf \: x = - 2 \\ \sf \: x = 3$

Solve each given equation and show your work. Tell whether it has one solution, an infinite number of solutions, or no solutions

WITCHER [35]

Solve 6x+4x-6=24+9x. Combine all the x terms on one side and all the constants on the other:

10x-9x = 24+6, or x = 30. ONE soution.

Solve 4x+8=2x+7 +2x-20. Combine all the x terms on one side and all the constants on the other: 4x - 2x - 2x = 7 - 20 - 8 => 0 = -21

This is NEVER true, so 4x+8=2x+7 +2x-20 has NO SOLUTION.

Please try solving equation B yourself. Then I'd gladly comment on your work.

Answer:

PR= 4.2 AC= 18

Step-by-step explanation:

1)divide by same sides

QP/GF

3/5=0.6

in order to get PR

7(GH) *0.6 =4.2

BA/ML

30/50=0.6

in order to get AC

30(LN) * 0.6= 18
