Which of the following expressions contains exactly two terms?
monomial |
|
polynomial |
|
quadratic |
|
binomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
Solve for x:
-9x + 3 = -2 - x
| \(\frac{1}{6}\) | |
| \(\frac{2}{9}\) | |
| \(\frac{5}{8}\) | |
| -1\(\frac{3}{4}\) |
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.
-9x + 3 = -2 - x
-9x = -2 - x - 3
-9x + x = -2 - 3
-8x = -5
x = \( \frac{-5}{-8} \)
x = \(\frac{5}{8}\)
If a = c = 1, b = d = 7, and the blue angle = 71°, what is the area of this parallelogram?
| 81 | |
| 15 | |
| 7 | |
| 9 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 1 x 7
a = 7
The formula for the area of a circle is which of the following?
c = π d2 |
|
c = π r |
|
c = π d |
|
c = π r2 |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
