A trapezoid is a quadrilateral with one set of __________ sides.
equal length |
|
right angle |
|
equal angle |
|
parallel |
A trapezoid is a quadrilateral with one set of parallel sides.
On this circle, line segment AB is the:
radius |
|
chord |
|
circumference |
|
diameter |
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 the base of this triangle is 9 and the height is 2, what is the area?
| 42 | |
| 9 | |
| 67\(\frac{1}{2}\) | |
| 27 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 9 x 2 = \( \frac{18}{2} \) = 9
Simplify (y + 2)(y + 2)
| 98 | |
| y2 + 4y + 4 | |
| y2 - 4y + 4 | |
| y2 - 4 |
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:
(y + 2)(y + 2)
(y x y) + (y x 2) + (2 x y) + (2 x 2)
y2 + 2y + 2y + 4
y2 + 4y + 4
If a = c = 4, b = d = 3, what is the area of this rectangle?
| 63 | |
| 12 | |
| 4 | |
| 32 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 4 x 3
a = 12
