If side x = 12cm, side y = 8cm, and side z = 8cm what is the perimeter of this triangle?
| 27cm | |
| 32cm | |
| 34cm | |
| 28cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 12cm + 8cm + 8cm = 28cm
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
addition |
|
pairs |
|
division |
|
exponents |
When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
The endpoints of this line segment are at (-2, -8) and (2, 2). What is the slope of this line?
| -3 | |
| 2\(\frac{1}{2}\) | |
| -\(\frac{1}{2}\) | |
| 2 |
The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, -8) and (2, 2) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(2.0) - (-8.0)}{(2) - (-2)} \) = \( \frac{10}{4} \)A(n) __________ is to a parallelogram as a square is to a rectangle.

triangle |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
On this circle, a line segment connecting point A to point D is called:
radius |
|
diameter |
|
chord |
|
circumference |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
