If AD = 28 and BD = 24, AB = ?
| 12 | |
| 9 | |
| 4 | |
| 14 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDOn this circle, line segment CD is the:
diameter |
|
radius |
|
chord |
|
circumference |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
If a = 7, b = 1, c = 1, and d = 4, what is the perimeter of this quadrilateral?
| 17 | |
| 13 | |
| 24 | |
| 16 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 7 + 1 + 1 + 4
p = 13
Solve for x:
-5x - 3 > 6 - x
| x > -2\(\frac{1}{4}\) | |
| x > -\(\frac{1}{2}\) | |
| x > 5 | |
| x > \(\frac{8}{9}\) |
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 > sign and the answer on the other.
-5x - 3 > 6 - x
-5x > 6 - x + 3
-5x + x > 6 + 3
-4x > 9
x > \( \frac{9}{-4} \)
x > -2\(\frac{1}{4}\)
