If BD = 4 and AD = 11, AB = ?
| 9 | |
| 7 | |
| 17 | |
| 20 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
Order the following types of angle from least number of degrees to most number of degrees.
right, obtuse, acute |
|
acute, right, obtuse |
|
acute, obtuse, right |
|
right, acute, obtuse |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
pairs |
|
division |
|
addition |
|
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.)
Solve for y:
8y - 8 = -5 - y
| -1 | |
| \(\frac{1}{3}\) | |
| -1\(\frac{3}{5}\) | |
| 2\(\frac{1}{4}\) |
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 equal sign and the answer on the other.
8y - 8 = -5 - y
8y = -5 - y + 8
8y + y = -5 + 8
9y = 3
y = \( \frac{3}{9} \)
y = \(\frac{1}{3}\)
