Which types of triangles will always have at least two sides of equal length?
equilateral, isosceles and right |
|
isosceles and right |
|
equilateral and isosceles |
|
equilateral 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 b:
-2b - 7 < 7 + 8b
| b < 1 | |
| b < -4 | |
| b < \(\frac{2}{3}\) | |
| b < -1\(\frac{2}{5}\) |
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.
-2b - 7 < 7 + 8b
-2b < 7 + 8b + 7
-2b - 8b < 7 + 7
-10b < 14
b < \( \frac{14}{-10} \)
b < -1\(\frac{2}{5}\)
If BD = 23 and AD = 30, AB = ?
| 6 | |
| 7 | |
| 18 | |
| 16 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDSimplify 3a x 9b.
| 27ab | |
| 27a2b2 | |
| 12ab | |
| 27\( \frac{a}{b} \) |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
3a x 9b = (3 x 9) (a x b) = 27ab
On this circle, line segment CD is the:
circumference |
|
diameter |
|
radius |
|
chord |
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).
