Answer:

194.

Step-by-step explanation:

x = (7+4√3)

x^2 = x = (7+4√3)^2

= 49 + 48 + 56√3

= 97 + 56√3

x^2 + 1/x^2 = 97 + 56√3 + 1/(97 + 56√3)

= 194.

Solve for x -16=8x/5

torisob [31]

-16 = 8x/5......8x/5 is the same as 8/5(x)

-16 = (8/5)x...divide both sides by 8/5
-16 / (8/5) = x
-16 * 5/8 = x
-80/8 = x
-10 = x <===
