If the length of AB equals the length of BD, point B __________ this line segment.
intersects |
|
bisects |
|
midpoints |
|
trisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
division |
|
exponents |
|
pairs |
|
addition |
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.)
What is 9a6 + 5a6?
| 4 | |
| a612 | |
| 14 | |
| 14a6 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
9a6 + 5a6 = 14a6
If a = -3 and x = 9, what is the value of -6a(a - x)?
| 63 | |
| -28 | |
| -216 | |
| 84 |
To solve this equation, 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.)
-6a(a - x)
-6(-3)(-3 - 9)
-6(-3)(-12)
(18)(-12)
-216
The dimensions of this cube are height (h) = 6, length (l) = 8, and width (w) = 1. What is the volume?
| 486 | |
| 96 | |
| 48 | |
| 32 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 8 x 1
v = 48
