Which of the following statements about a parallelogram is not true?
a parallelogram is a quadrilateral |
|
opposite sides and adjacent angles are equal |
|
the area of a parallelogram is base x height |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
If a = c = 9, b = d = 8, what is the area of this rectangle?
| 72 | |
| 18 | |
| 63 | |
| 9 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 9 x 8
a = 72
A(n) __________ is two expressions separated by an equal sign.
problem |
|
formula |
|
equation |
|
expression |
An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
Which of the following expressions contains exactly two terms?
polynomial |
|
binomial |
|
quadratic |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If a = 3, b = 9, c = 8, and d = 8, what is the perimeter of this quadrilateral?
| 19 | |
| 9 | |
| 28 | |
| 26 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 3 + 9 + 8 + 8
p = 28
