A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If side x = 6cm, side y = 7cm, and side z = 14cm what is the perimeter of this triangle?
| 32cm | |
| 27cm | |
| 19cm | |
| 29cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 6cm + 7cm + 14cm = 27cm
Simplify (y - 5)(y - 6)
| y2 - 11y + 30 | |
| y2 + 11y + 30 | |
| y2 - y - 30 | |
| y2 + y - 30 |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses:
(y - 5)(y - 6)
(y x y) + (y x -6) + (-5 x y) + (-5 x -6)
y2 - 6y - 5y + 30
y2 - 11y + 30
A coordinate grid is composed of which of the following?
x-axis |
|
y-axis |
|
all of these |
|
origin |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
If a = c = 9, b = d = 3, what is the area of this rectangle?
| 27 | |
| 42 | |
| 3 | |
| 40 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 9 x 3
a = 27
