Plz ! i’m rly stuck on this question.

C

Step-by-step explanation:

Rearrange the quadratic into standard form by subtracting d from both sides

- 16t² + 8t - d = 0 ← in standard form

with a = - 16, b = 8, c = - d

Using the quadratic formula to solve for t

t = (- 8 ± )/ - 32

 = ( - 8 ± )/ - 32

  = ( - 8 ± ) / - 32

  = ( - 8 ± 8) / - 32

  = ±

  = ±

  = ±

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)
