Which of the following expressions contains exactly two terms?
quadratic |
|
binomial |
|
polynomial |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
What is the area of a circle with a diameter of 10?
| 7π | |
| 6π | |
| 25π | |
| 16π |
The formula for area is πr2. Radius is circle \( \frac{diameter}{2} \):
r = \( \frac{d}{2} \)
r = \( \frac{10}{2} \)
r = 5
a = πr2
a = π(52)
a = 25π
If angle a = 54° and angle b = 62° what is the length of angle c?
| 64° | |
| 79° | |
| 106° | |
| 74° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 54° - 62° = 64°
A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
triangle |
|
rhombus |
|
quadrilateral |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Which of the following is not true about both rectangles and squares?
the perimeter is the sum of the lengths of all four sides |
|
all interior angles are right angles |
|
the lengths of all sides are equal |
|
the area is length x width |
A rectangle is a parallelogram containing four right angles. Opposite sides (a = c, b = d) are equal and the perimeter is the sum of the lengths of all sides (a + b + c + d) or, comonly, 2 x length x width. The area of a rectangle is length x width. A square is a rectangle with four equal length sides. The perimeter of a square is 4 x length of one side (4s) and the area is the length of one side squared (s2).
