Maggie stacked a box that was 83 centimeters (cm) tall on top of a box that was 128 centimeters. how tall was the stack of boxes in meters and centimeters?

The height of the stack is given by the sum of the heights of the boxes:

In order to convert this result in meter, remember that

So, to covert form centimeters to meters we have to multiply by 0.01 (or divide by 100).

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)
