The dimensions of this cube are height (h) = 9, length (l) = 3, and width (w) = 1. What is the surface area?
| 190 | |
| 152 | |
| 78 | |
| 202 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 3 x 1) + (2 x 1 x 9) + (2 x 3 x 9)
sa = (6) + (18) + (54)
sa = 78
Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
deconstructing |
|
factoring |
|
squaring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.

quadrilateral |
|
trapezoid |
|

If a = c = 6, b = d = 3, what is the area of this rectangle?
| 16 | |
| 14 | |
| 18 | |
| 24 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 6 x 3
a = 18
On this circle, line segment CD is the:
diameter |
|
chord |
|
radius |
|
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).
