Answer:
x²+1/x² = 51
Explanation:
Given x - 1/x = 7 ---(1)
We know the algebraic identity:
a²+b²-2ab = (a-b)²
Or
a²+b² = (a-b)²+2ab
Now,
x²+1/x²
= (x-1/x)²+2*x*(1/x)
= (x-1/x)²+2
:7²+2 [ from (1)] =
= 49+2
= 51
Therefore,
x²+1/x² = 51
The answer is 10 because if you round It Off it will be 5 + 10 equal 15 Sultan is the answer to your question
Answer:
Step-by-step explanation:
The length of the trail is obtained by the definition of sine, where height is the opposite leg and length is the hypotenuse:
The length of the trail is:
Y = 7.25x
Where x = hours.
You can get this by dividing the amount by the amount of hours in each pair.
31 degrees (vertically opposite angle)
