If the length of AB equals the length of BD, point B __________ this line segment.
intersects |
|
trisects |
|
midpoints |
|
bisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
If b = 6 and x = 4, what is the value of -b(b - x)?
| -240 | |
| 315 | |
| 140 | |
| -12 |
To solve this equation, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
-b(b - x)
-1(6)(6 - 4)
-1(6)(2)
(-6)(2)
-12
If side x = 7cm, side y = 6cm, and side z = 15cm what is the perimeter of this triangle?
| 30cm | |
| 28cm | |
| 38cm | |
| 33cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 7cm + 6cm + 15cm = 28cm
The dimensions of this cube are height (h) = 1, length (l) = 1, and width (w) = 7. What is the volume?
| 160 | |
| 64 | |
| 216 | |
| 7 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 1 x 7
v = 7
If a = c = 2, b = d = 6, and the blue angle = 68°, what is the area of this parallelogram?
| 12 | |
| 36 | |
| 42 | |
| 40 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 2 x 6
a = 12
