If side x = 8cm, side y = 15cm, and side z = 12cm what is the perimeter of this triangle?
| 36cm | |
| 23cm | |
| 26cm | |
| 35cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 8cm + 15cm + 12cm = 35cm
A coordinate grid is composed of which of the following?
y-axis |
|
x-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.
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Inside |
|
Odd |
|
Last |
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.
Solve for z:
-5z - 8 > -5 + 2z
| z > -3 | |
| z > 1\(\frac{1}{6}\) | |
| z > -\(\frac{3}{7}\) | |
| z > -\(\frac{3}{8}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the > sign and the answer on the other.
-5z - 8 > -5 + 2z
-5z > -5 + 2z + 8
-5z - 2z > -5 + 8
-7z > 3
z > \( \frac{3}{-7} \)
z > -\(\frac{3}{7}\)
Which of the following statements about a parallelogram is not true?
a parallelogram is a quadrilateral |
|
the area of a parallelogram is base x height |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
opposite sides and adjacent angles are equal |
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).
