To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Last |
|
Inside |
|
First |
|
Odd |
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.
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.)
If a = 6, b = 6, c = 5, and d = 7, what is the perimeter of this quadrilateral?
| 16 | |
| 15 | |
| 22 | |
| 24 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 6 + 6 + 5 + 7
p = 24
What is 8a4 + 9a4?
| 17a4 | |
| a48 | |
| -1 | |
| 72a4 |
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.
8a4 + 9a4 = 17a4
When two lines intersect, adjacent angles are __________ (they add up to 180°) and angles across from either other are __________ (they're equal).
obtuse, acute |
|
supplementary, vertical |
|
acute, obtuse |
|
vertical, supplementary |
Angles around a line add up to 180°. Angles around a point add up to 360°. When two lines intersect, adjacent angles are supplementary (they add up to 180°) and angles across from either other are vertical (they're equal).
