What is the circumference of a circle with a diameter of 13?
| 2π | |
| 19π | |
| 13π | |
| 24π |
The formula for circumference is circle diameter x π:
c = πd
c = 13π
Which types of triangles will always have at least two sides of equal length?
equilateral and isosceles |
|
equilateral, isosceles and right |
|
equilateral and right |
|
isosceles and right |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
Solve for x:
6x + 1 = \( \frac{x}{6} \)
| -1\(\frac{19}{29}\) | |
| -7\(\frac{5}{7}\) | |
| -\(\frac{6}{35}\) | |
| -1\(\frac{9}{55}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
6x + 1 = \( \frac{x}{6} \)
6 x (6x + 1) = x
(6 x 6x) + (6 x 1) = x
36x + 6 = x
36x + 6 - x = 0
36x - x = -6
35x = -6
x = \( \frac{-6}{35} \)
x = -\(\frac{6}{35}\)
