Answer:
x= 2.28
or, x= 0.219
Step-by-step explanation:
2x²-5x+1 =0
a= 2, b= -5 and c= 1
x= (-b <u>+</u> √(b²-4ac))/2a
= (5 <u>+</u> √(25-8))/4
= (5 <u>+</u> √17)/4
Answer:

Step-by-step explanation:

Answer:
c = 5
Step-by-step explanation:
IT'S THE THREE FOUR FIVE TRIANGLE!!
3^2 + 4^2 = c^2
√25 = c
c = 5
16.5 because it would 165 divided by 10, so if you were to round it’s 17 because you can’t really get half a person.
The sum of a polygon's angles are 540.
When you add all the angles together here, you get 456.
Now subtract 456 from 540.
540 - 456 = 84
