(x + 1/x)² = 3 | √
<u>x + 1/x</u> = √3
According to short multiplication formula:
(a + b)³ =a³ + 3a²b + 3ab² + b³
x³ + 1/x³ = (x)³ + (1/x)³ = (x + 1/x)³ - 3x²/x - 3x/x² =
= (x + 1/x)³ - 3x - 3/x = (<u>x + 1/x</u>)³ - 3(<u>x + 1/x</u>) =
= (√3)³ - 3√3 = 3√3 - 3√3 = 0
If (x + 1/x)² = 3 the value of x³ + 1/x³ is 0.

Answer:
b
Step-by-step explanation:
Answer:
x = 61°
y = 29°
Step-by-step explanation:
Since x°+29° is a right angle (90°), you would have to subtract 29 from 90 to get x.
90 - 29 = x
90 - 29 = 61
x = 61°
For y: You can infer that y°+x°=90° as well because the angles are corresponding angles. So to find y°, you would do the same thing as finding x.
90 - x = y
90 - 61 = 29
y = 29°
Hope this helps :)
