A trapezoid is a quadrilateral with one set of __________ sides.
equal angle |
|
parallel |
|
equal length |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
Solve for a:
7a - 3 = \( \frac{a}{1} \)
| \(\frac{1}{2}\) | |
| 4\(\frac{11}{13}\) | |
| 4 | |
| \(\frac{36}{43}\) |
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.
7a - 3 = \( \frac{a}{1} \)
1 x (7a - 3) = a
(1 x 7a) + (1 x -3) = a
7a - 3 = a
7a - 3 - a = 0
7a - a = 3
6a = 3
a = \( \frac{3}{6} \)
a = \(\frac{1}{2}\)
Solve for a:
-3a - 5 = 2 - 5a
| -\(\frac{1}{9}\) | |
| -2 | |
| 3\(\frac{1}{2}\) | |
| -1\(\frac{1}{6}\) |
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.
-3a - 5 = 2 - 5a
-3a = 2 - 5a + 5
-3a + 5a = 2 + 5
2a = 7
a = \( \frac{7}{2} \)
a = 3\(\frac{1}{2}\)
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Last |
|
Odd |
|
Inside |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
If angle a = 21° and angle b = 40° what is the length of angle c?
| 111° | |
| 80° | |
| 119° | |
| 104° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 21° - 40° = 119°
