Which of the following expressions could be used to find the perimeter of this figure?

OP= 4(18 mm) + 2(24 mm)
O P= 18 mm + 24 mm
O P= 2(18 mm) + 4(24 mm)
P= (18 mm (24 mm)

answer: asdfghjkl,mnbv

step-by-step explanation:

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)

the answer is 62.8 cubic units
