<h3>Final value : x² -9x - 11</h3>

<h3>Step by step </h3>
2x + 1 = ⅕ × (x² + x - 6)
2x + 1 = ⅕x² + ⅕x - 6/5
1/5x² +1/5x - 2x - 6/5 - 1 = 0
1/5x² -9/5x - 11/5 = 0
x² - 9x - 11 = 0. #times by 5

<span>3 of the 20 toothbrushes are defective, so the initial probability of selecting a defective toothbrush on the first try is 3/20. After that, there will be 2 defective toothbrushes in the remaining 19, so the probability of selecting one of those on the 2nd try will be 2/19. To get the probability of those two events happening sequentially, we multiply the two probabilities. Thus (3/20)*(2/19) = 6/380 = 0.0157, or about 1.6%.</span>
The general Formula for a decreasing Annuity is:
For this example we have:
P = 78,000
n = 7*4 = 28
i = 8%/4 = 2% = 0.02
After substituting you can find value for R, rent.
Answer:
(x - 1) / (x + 3).
Step-by-step explanation:
x²+5x-6/x²+9x+18
Factoring top and bottom:
= (x + 6)(x - 1) / (x + 6)(x + 3) (x + 6) is common, so:
= (x - 1) / (x + 3) (answer).
