90% of 20 is x
20 times 90% is x
20 times .9 equals 18
The restaurant served 18 salmon filets.
(<em>a</em> ² + <em>b</em> ²) / (<em>ab</em>) = <em>a</em>/<em>b</em> + <em>b</em>/<em>a</em> = (√3 - √2) + 1/(√3 - √2)
Rationalize the denominator of the second term:
1/(√3 - √2) • (√3 + √2)/(√3+√2) = (√3 + √2)/((√3)² - (√2)²) = √3 + √2
So we have
(<em>a</em> ² + <em>b</em> ²) / (<em>ab</em>) = (√3 - √2) + (√3 + √2) = 2√3

Answer:
It will take 8 years.
Step-by-step explanation:
If the plant is already 14 inches and you want it to grow up to 38, then we subtract 14 from 38 and then divide the answer by 3 because in each year the plant will grow 3 inches, so then you get 8, which is the numbers of years.
38 - 14 = 24
24/3 = 8
