Answer:
Correct answer: x₁ = 1 / √3 = √3 / 3 or x₂ = - 1 / √3 = - √3 / 3
Step-by-step explanation:
Given:
3 x⁴ + 14 x² - 5 = 0 biquadratic equation
this equation is solved by a shift x² = t and get:
3 t² + 14 t - 5 = 0
t₁₂ = (-14 ± √14² - 4 · 3 · 5) / 2 · 3 = (-14 ± √196 + 60) / 6
t₁₂ = (-14 ± √256) / 6 = (-14 ± 16) / 6
t₁ = -5 or t₂ = 1 / 3
the solution t₁ = -5 is not accepted because it cannot be x² = -5
we accepted t₂ = 1 / 3
x² = 1 / 3 ⇒
x₁ = 1 / √3 = √3 / 3 or x₂ = - 1 / √3 = - √3 / 3

Answer:
The value of x is 5 centimeters.
Therefore, option 3 is correct.
Step-by-step explanation:
A triangle has three sides 3,x and 4 cms
Since the triangle is right angle triangle so, it will follow the Pythagoras theorem:
(1)
We have been given three sides x,3 and 4
On substituting the values in (1) we get:
Hence, the value of x is 5 centimeters.
Therefore, option 3 is correct.

Answer:
A: venti has a better unit rate at .2275 cents per ounce
B: to get the unit rate you divide the cost by the number of ounces.
Step-by-step explanation:
tall = .2958 cents per ounce
grande = .2656 cents per ounce
venti = .2275 cents per ounce
