I could be wrong, but I think it's D
answer:
each friend would have 3 and 1/2 bottles of juice meaning each friend would have 3 fully empty bottles.
We have
(a + b)² = a² + 2ab + b²
so that with a = x² and b = 5, we have
x⁴ + 10x² + 25 = (x² + 5)²
Next, we have
a² - b² = (a - b) (a + b)
so that with a = x and b = √5 i,
x² + 5 = x² - (-5) = (x - √5 i) (x + √5 i)
So, the complete factorization over the complexes is
(x - √5 i)² (x + √5 i)²
Answer:
X=120
X=54

Answer:
The value of SecФ is
.
Step-by-step explanation:
Given as for trigonometric function :
tan²Ф = 
Or, tanФ = 
∵ tanФ = 
So,
= 
So, Hypotenuse² = perpendicular² + base²
or, Hypotenuse² = (
)² + (
)²
Or, Hypotenuse² = 3 + 8 = 11
Or, Hypotenuse = (
)
Now SecФ = 
or, SecФ =
= 
<u>Second Method</u>
Sec²Ф - tan²Ф = 1
Or, Sec²Ф = 1 + tan²Ф
or, Sec²Ф = 1 + 
Or, Sec²Ф = 
Or, SecФ = 
Hence The value of SecФ is
. Answer
