Step-by-step explanation:
Using the rules of exponents

= ![\sqrt[n]{a^{m} }](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%20%7D)
Given
= 
= ![\frac{1}{\sqrt[b]{y^{a} } }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%5Bb%5D%7By%5E%7Ba%7D%20%7D%20%7D)
Answer:
(x + 5)(x + 2) / (x³ - 9x)
Step-by-step explanation:
We need to find a common denominator.
factor each denominator
x² - 3x = x(x - 3)
x³ - 9x = x(x² - 9) = x(x + 3)(x - 3)
x² - 9 = (x + 3)(x - 3)
As the factors of the first and third denominators are subsets of the second, the second is the LCD. This immediately eliminates the last two options as possible solutions.
Now we multiply each term by the missing factor over itself (1)
<u>(2x + 5)(x + 3)</u> - <u>(3x + 5)</u> - <u>(x + 1)(x)</u>]
(x² - 3x)<u>(</u>x + 3<u>)</u> (x³ - 9x) (x² - 9)(x)
[(2x² + 11x + 15) - (3x + 5) - (x² + x)] / (x³ - 9x)
[2x² + 11x + 15 - 3x - 5 - x² - x] / (x³ - 9x)
(x² + 7x + 10) / (x³ - 9x)
(x + 5)(x + 2) / (x³ - 9x)
Answer:
There is no following figure so the answer is none.
Step-by-step explanation:
Given:
cost of haircut : $15
tip: 20% of cost
15 + (15 x 20%) ⇒ 15 + 3 = 18
Vince gave $18 to his barber from the haircut and tip.
