Answer:

<u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>

Step-by-step explanation:

Given :

  • 3x² - 24x + 12

Divide throughout by 3 to simplify :

  • 1/3 x (3x² - 24x + 12)
  • x² - 8x + 4

Using the Quadratic Formula :

  • x = -b ± √b² - 4ac / 2a
  • x = -(-8) ± √(-8)² - 4(1)(4) / 2(1)
  • x = 8 ± √64 - 16 / 2
  • x = 8 ± √48 / 2
  • x = 8 ± 4√3 / 2
  • x = 4 ± 2√3

Factors are :

  • <u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>

<h2>ANSWER: </h2>

\large\blue{ ──────────────────────}

Simplifying:

  • 3x2 + 24x + -12 = 0

Reorder the terms:

  • -12 + 24x + 3x2 = 0

Solving:

  • -12 + 24x + 3x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '3'.

  • 3(-4 + 8x + x2) = <u>0</u>

The population of winnecumma, Nevada, is growing at a rate of 5% each year. If the population is 8742, how many years(3 decimal
sweet-ann [11.9K]
Current population = P = 8742
Population after t years = A = 12000
Growth rate = r = 5%

We are to find the number of years it takes the population to grow to 12,000.

So, we can write:

A=P(1+r)^{t}

Using the values, we get:

12000=8742(1+0.05)^{t}  \\  \\ &#10; \frac{12000}{8742}= (1.05)^{t} \\  \\ &#10;t=6.492

This means, it will take 6.492 years for the population to grow to 12,000.

Which number line represents the solution set for the inequality –(1/2)x ≥ 4?
sergejj [24]

When the sign is ≤ or ≥ (less/greater than or equal to), the dot is filled in.

When the sign is < or >, the dot is not filled in and looks like this o

To find out which number line represents the solution set, simplify the inequality and isolate x

-\frac{1}{2}x\geq4    Multiply -2 on both sides to get rid of -1/2

(-2)(-\frac{1}{2}x)\geq4(-2)

x ≤ -8       (The sign flips when you multiply/divide a negative number on both sides of the inequality)

so you get x is greater than or equal to -8, so you have a filled in circle on -8, and the arrow should be going to the right since x is greater than -8
