You estimate 16 and 2 so it is 20+2=22
x^2 - x/5 + 2 = 0
Subtract 2 from both sides.
x^2 - x/5 = -2
Multiply all terms by 5.
5x^2 - x = -10
Add 10 to both sides.
5x^2 - x + 10 = 0
We can now apply the quadratic formula:

1 ± (√ 1 - 200) / 10
1 ± √-199 / 10
1 ± i√199 / 10
<h3><u>The solutions are equal to 1 + or - i times the square root of 199 divided by 10.</u></h3>
Answer:
the answer is x ≤ 2
Step-by-step explanation:
very easy
The answer is 6 because the absolute value of 8 is 8 and the absolute value of -3 is 3 so using BEDMAS we get 8 - (2 x 3) + 4 = 6
