| 19 | |
| 1 | |
| 20 | |
| 4 |

monomial |
|
binomial |
|
quadratic |
|
polynomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
A coordinate grid is composed of which of the following?
y-axis |
|
all of these |
|
origin |
|
x-axis |
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.
If a = 4 and z = -4, what is the value of -4a(a - z)?
| -136 | |
| -50 | |
| -128 | |
| 192 |
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.)
-4a(a - z)
-4(4)(4 + 4)
-4(4)(8)
(-16)(8)
-128
