-4 5/12

Step-by-step explanation:

Add the fractions

-7 2/3 -5 1/2 = -13 3/18

-13 1/6 + 8 3/4 = -4 5/12

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)

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
