A b c or d ? The topic is inequalities

B

Step-by-step explanation:

closed circle for "less than or equal to" or "greater than or equal to"

x is less than or = to 10

B

Step-by-step explanation:

Since x is less than or equal to 18, you would eliminate D and C since they show x is greater than 18. You would eliminate A too since while it is showing less than 18, it is not showing that is is equal to 18.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
