Which expression is equivalent to 12•2•3

4 x 3 x 2 x 3

Step-by-step explanation:

4 x 3 = 12

12 x 2 = 24

24 x 3 = 36

It doesn't matter what order it will come out to be 36 in every situation, since PEMDAS isn't needed.

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)

2x^2+5x+17
