Answer:
B. 85
Step-by-step explanation:
A Triangle is 270 degrees so just add the two given numbers , subtract them from 27, and you get 85.
6 girls have brown hair, and you want to know the probability of finding one without brown hair, so you take the population and subtract brown hair, or 22. You have a 22/28 chance of picking a girl without brown hair, simplified to 11/14.
Answer:
The answer to your question is 2(x - 9/2)(x - 3/5)
Step-by-step explanation:
Polynomial 20x² - 102x + 54
Process
1.- Find the Greatest Common Factor
20 102 54 2
10 51 27 2
5 51 27 3
5 17 9 3
5 17 3 3
5 17 1 5
1 17 17
1
GCF = 2
2.- Factor 2
2(10x² - 51x + 27)
3.- Factor 10x² - 51x + 27
Use the general formula to solve this equation
x = 
a = 10 b = -51 c = 27
x = 
-Simplification
x = 
-Result
x₁ = 9/2 x₂ = 3/5
(x - 9/2) (x - 3/5)
4.- Answer
2(x - 9/2)(x - 3/5)
