If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
intersects |
|
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.
A trapezoid is a quadrilateral with one set of __________ sides.
right angle |

A trapezoid is a quadrilateral with one set of parallel sides.
A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
rhombus |
|
quadrilateral |
|
triangle |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Find the value of b:
2b + x = -1
7b + 2x = 2
| 1\(\frac{1}{3}\) | |
| \(\frac{1}{3}\) | |
| -\(\frac{6}{23}\) | |
| -2\(\frac{16}{21}\) |
You need to find the value of b so solve the first equation in terms of x:
2b + x = -1
x = -1 - 2b
then substitute the result (-1 - 2b) into the second equation:
7b + 2(-1 - 2b) = 2
7b + (2 x -1) + (2 x -2b) = 2
7b - 2 - 4b = 2
7b - 4b = 2 + 2
3b = 4
b = \( \frac{4}{3} \)
b = 1\(\frac{1}{3}\)
A cylinder with a radius (r) and a height (h) has a surface area of:
π r2h |
|
π r2h2 |
|
4π r2 |
|
2(π r2) + 2π rh |
A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.
