X^2 - 14x + 42 = 0
x^2 - 14x = -42
x^2 - 14x + 49 = 49 - 42
(x - 7)^2 = 7
x - 7 = (+-) sqrt 7
x = 7 (+-) sqrt 7
solutions are : x = 7 + sqrt 7 and x = 7 - sqrt 7
Number of trees that are grew more than 3 feet = 10 + 35 = 45
Number of trees that grew more than 3 feet and is more than 50 yards away = 35
P(3 feet and more than 50 yards) = 35/45 = 7/9
Answer: 7/9
28/20 in simplest form is: 7/5
70/50 in simplest form is 5/7
Because,
28/20 divided by 2 is 14/10, divided by 2 again is: 7/5
70/50 divided by 2 is 25/35, divided by 2 again is: 5/7
Answer:
1350
Step-by-step explanation:
60(pi/180)=pi/3
.5(12^2)(pi/3)
72(pi/3)
24pi
