Step-by-step explanation:
Answer:
x = 1 + i sqrt(7/2) or x = 1 - i sqrt(7/2)
Step-by-step explanation:
Solve for x:
2 x^2 - 4 x + 9 = 0
Divide both sides by 2:
x^2 - 2 x + 9/2 = 0
Subtract 9/2 from both sides:
x^2 - 2 x = -9/2
Add 1 to both sides:
x^2 - 2 x + 1 = -7/2
Write the left hand side as a square:
(x - 1)^2 = -7/2
Take the square root of both sides:
x - 1 = i sqrt(7/2) or x - 1 = -i sqrt(7/2)
Add 1 to both sides:
x = 1 + i sqrt(7/2) or x - 1 = -i sqrt(7/2)
Add 1 to both sides:
Answer: x = 1 + i sqrt(7/2) or x = 1 - i sqrt(7/2)
Answer:
Given the expression: log 2 -log 6
Use the logarithmic rule :


Use the above rule to solve the expression:
[∴

or
value of : log 2 -log 6 = 0.30102999566 - 0.77815125038 = -0.47712125472
A rectangle has four sides, two equal to the width and two equal to the length. So, the perimeter is

If we know that the width is 5, and the perimeter is 125, we have

In your case, the unkown is called x, but the concept is the same:

where x is the length of the rectangle.
